Oil, med and dry was basically figured by length.
(this is from the book Revolutions2)
Oil (long oil) were lanes oiled 35 to 45 feet.
Med. were lanes oiled 25 to 35 feet.
Dry (very short oil) was 18 to 25 feet.
heres a quote from a interesting article on patterns.
"the overall volume of the shot probably has the least affect, as the length that the conditioner is applied can make the "volume" almost meaningless."
Click here for story (http://"http://bowlingknowledge.info/index.php?option=com_content&task=view&id=164&Itemid=46")
As used in BTM current issue
Oily is a 44' oil (High Street)
Medium 41' oil (Main Street)
Dry 38' oil (Easy Street)
These are the Kegel Navigation Recreation Series of patterns.
you can see them here.

In USBowler Magazine Vol.2, No.3 Spring 2007
Page 12 Coach's Corner They have a article "Everything you wanted to know about lane conditions"
In it they say
"A layer of oil 100-plus units would be considered "Heavy oil" and anything less then 50 units probably would be "Light oil".
(A 100 units is bunch!)
As for the length's they have
Long oil as 40 feet or longer
Medium oil as 35' to 45' feet or more
Short oil 35 feet or less

You can make 44 pattern looks like 38 feet medium shot, or you can put a 36 feet so called short pattern which will make balls considerably straight..

Distance is 1 factor. Kegel uses microliters as measurements of unit for oil. Does anyone know what is the convertion of microliters to Units of oil?
A unit of oil is more a measurement of thickness, than amount. Example a piece of typing paper is about 400 units thick.
"A "unit" of oil is defined by the American Bowling Congress (ABC) and Women's International Bowling Congress (WIBC) as 0.0167 cubic centimeters of oil evenly spread over a 1 sq. ft. surface, which equates to a film of oil about 7 millionths of an inch thick." (Computerized Lane Inspection Program Manual at bowl.com)
so 0.0167 cubic centimeters converts to cubic 16.7 microliters [µL]
quote:
It's not about how much or how long, but where, the distribution! Taper, buff area, ratios, as well as the lane surface which will be applied.

They talk more about that in the article.

I used to help program patterns into our machine where my shop was and we played with several different oils which consisted of different densities which affected a pattern tremendously.

Based on experience, this is very true due to different densities of oil that can be utilized along with the surface on which it is applied. "X" amount of units at say 65 density at 44ft on new Anvilane will play completely different then the same oil, distance and units applied on 40yr old wood.
Unfortunately, we'd also need to know the ratio that the oil is dispersed as that is controlled by a machine as well. We can dictate the amount of oil applied by altering the release pressure of the jets/wicks. Just thought I'd share...

or at least there is no way to easily describe a pattern unless everyone bowls on it... such as the pba patterns as they are generally at a fixed range of oil amounts and the same taper (only lane surface is different)
there are just too many variables.
I was just trying to figure out ball reviews for it was said ball 'x' was thrown on 42 feet and 50 units in the middle. i wanted to know just what to compare that to. medium, heavy.... or what... i know taper will be the most important factor but i dont know what it was.... assuming BTM uses a house style pattern?

The best description of heavy oil I saw was "Any oil more than what you normally bowl on".
As for BTM in the current issue these are the patterns they used.
Oily is a 44' oil (High Street)
Medium 41' oil (Main Street)
Dry 38' oil (Easy Street)
These are the Kegel Navigation Recreation Series of patterns.
you can see them here.
http://www.kegel.net/patternlibrary/default.asp
These according to the kegel site are types of house patterns.
you can also look up other patterns like other house patterns and see how they compare to those.
If you know your lane type,machine and oil used in your home house, you can see some of the other house patterns they have.

Ain't that the truth. Same thing goes for light oil or dry. It's all based on perception, and personal experience.

24ml+ = heavy (rarely encountered)
18-22ml = medium (most tournament patterns)
17 or less = light
This range is typical for most houses which fulfill sport bowling standards, and you feel the differences, esp. on longer patterns.
Oil viscosity is another serious influence - the more viscous the lane conditioner, the longer the pattern remains stable, but you also have more carrdown and even oil in the pins.

Dizzy, if you put 18-19ml on HPL, regardless of the length it's gonna be real DRY, not even close to medium
I usually go around 22-25ml range for a "medium pattern". Trust me, I'm preparing most of the patterns for our center. For Anvilanes, I totally agree it is just like you have stated.

I am not sure, but I think "units" and ml are just the same. Over here, we just measure the oil volume in ml, and this here is a rough estimate:

17 or less = light

A "Unit of oil" isn't the same as a "ml"(milliliter)
(UNIT=0.0167 ml of oil evenly spread over a 1 sq. ft. surface)
Those are total volumes of oil used per the whole lane.
(24ml (ml=milliliter) is about about 2/3rds of a shot glass of oil.)
Example- The Kegel High Street pattern uses a TOTAL OIL (mL):21.10 per lane

this is from a kegel white paper. "How to Read Lane Pattern Graphs - The Lane Tape Graph" By Brandy Padilla, Chemical Engineer and Safety Director
quote:
You may be wondering what a unit is? Let me explain. A unit is a measure of the amount of oil in an area of lane. It isn’t really as straightforward as one would hope, so it can be difficult to grasp. The USBC defines a unit as a measurement of dressing film thickness equivalent to 0.0167 cubic centimeters of dressing per square foot of lane surface. A decent rule of thumb is that 1 unit is 40 micro liters per board at the end of the pattern, and 1 unit is 120 micro liters per board near the arrows.
this don't make sense a unit is a fixed amount of oil per square foot.
How can one unit change from 40 to 120 from one end of the pattern to the other?
Just to make sure now
cubic centimeters(cc) and milliliters(ml) are the same amount
microliters(µL)
1cc = 1ml = 1000µL

I emailed kegel about this heres the reply.
-------------------------
Hello and thank you for your questions. I will do my best to answer them.
The microliters don't actually change. That was a very generalized rule of thumb passed along to me to help visualize the amount of conditioner in each area of the lane. It is more useful for a house pattern than for a sport or challenge pattern. The microliters per board are set in the machine and pattern so they would not change. As you said, it is a set amount of oil.
The rule of thumb is certainly not meant to be absolute it's just a very rudimentary generalization to illustrate the difference in the amount of conditioner applied in the front part of the lane versus the end of the pattern.
I hope this helps clarify. Please feel free to contact me with any additional questions.
Thank you again for your e-mail.
Kind regards,
Brandy

Going by this I'd say she took the "rule of thumb" out of it's original context. which made it look like 1 unit equaled 40 microliters at one end of the pattern and at the other end of the pattern 1 unit equaled 120 microliters .

Interesting...it may be a method of "their" measurement system that they use. I agree, mathematically it makes no sense. However, I can say this.
On an average, most patterns (more prevalent on synthetics) only physically apply oil to a certain distance and then the release of oil is stopped to where the machine is now just "buffing" in the rest. The oil tanks are no longer applying additional oil toward the end of a pattern or you would in turn could or would have a very heavy pattern. It's what we call blending in a pattern so it helps a ball transition from skid to hook and then have the backend clean so then it rolls/finishes. If a pattern is not blended well, this is typically when you see O/U from front to back (assuming the backends are clean as well).
There are some situations where oil can be utilized to a further distance due to the high friction of its surface (ie. old wood, worn out synthetics)
I wonder if this is what they're trying to say that in regards to 120 up front and 40 in the back.

Hey icewall,
That's pretty much the case. We've only tapped into oil patterns and not the bowler yet so hypothetically what's heavy to you or myself may not be to a rev dominant bowler.
I guess a decent definition of "heavy" would simply be when that particular bowler is not getting enough reaction in proportionate phases of skid/hook/roll. Hope this helps some...
