« on: January 22, 2007, 10:15:09 AM »
here is a link to the pattern...

 
http://pba.com/resources/oilpatterns/laneconditions.asp?ID=22http://

ive bowled forever but never really looked into reading graphs..is the darkest area where the most oil is,,and about forward and reverse application, can someone hit that subject aswell...

is the darkest area where the most oil is?

Yes that is the area that oil is put down in both forward and reverse.

The more forward loads you have the more oil you will have down lane in the buff out area cause it gets carried downlane by the buffing brush.

Reverse give the pattern it's hold and helps to increase the amount of oil in the heads since it is being carried back by the buffing brush.

There is more to it than that but I wanted to keep it simple.

Based on the spreadsheet this pattern would be very wet/dry due to the small forward volume with nothing outside 7L or 5R and high reverse volume. I would think it would require playing inside angles using the bounce that is outside 5. Lane surface and condition could change this though.

The funny thing about the pattern in the link that you posted is that it wouldn't be a USBC legal pattern. If you click the "click here to view the pattern" link it shows the actual loads that are applied and this particular pattern does not have any forward 2L - 2R loads. These 2-2 loads are needed to get the 3 unit minimum volume on the 2 board 1' from the end of the pattern.
I have never seen a pattern that didn't have at least 2 2-2 loads. In many cases at least 3 loads are needed to get the required 3 units.

thanks for the reply...i looked at the spreadsheet also, but it was more greek than the actual graph...thats what i was looking for, the best angle of attack with this pattern..

thanks

Something that many people overlook when looking at lane graphs is the speed of the machine.

There is a vast difference between a 40' long shot where the machine starts slow and gradually gets faster versus a fast machine that slows down gradually towards the end of the pattern.

Yes the speed of the machine has a large influence on the way the pattern will play.
I have seen many patterns but I have never seen anyone create one that the machine slows down as it moves down the lane. This would be stupid cause the lanes would play like they were in transition from the very start due to the higher volume of oil in the midlane. Carrydown would happen very quickly and even with fresh backends they would seem tight cause the ball can't read correctly when there is more oil down lane than there is in the heads. I have bowled on a couple of pattern where the speed stayed pretty constant and they played quite tough.
If you have ever actually bowled on a condition that the machine moved quicker downlane than it did in the heads you need to tell the pattern designer to get a clue. Creating a tough pattern is one thing but that is asinine.

Re Evolution:

Did you mean SLOW in the midlane and the end of the pattern?  

For house shots at least you want slower in the heads and faster towards the end of the pattern to create a consistent and predictable transition.  Sport shots, PBA patterns, and tougher shots in general can all have slow speed in general, but not as a rule.

When watching and analyzing the speed of a machine you want to watch the distance the machine travels before it speeds up to strip the backends (hopefully) and the differences in speed as it travels through the heads and midlane.  Slow speed doesn't neccessarily mean flood, but does spell trouble.  Fast speed as well doesn't mean light, but could also be difficult.  

To strikealot:

Laneplay on this pattern will be dictated by the surface you will be bowling on.  At 40 feet the breakpoint "should" be in the 9-11 board range.  How you get there depends on your style and lane topography.  It's hard to give laneplay advice based on a graph without knowing the surface.  All we can give is generalities, and I agree with ReEvolution that an inside angle will be the best place to start.  But remember, your line will change, and it will change quick. You may need to move way deep inside or way outside as the lane breaks down.

yes that is what I meant, I was just so stunned by what was said I was not thinking straight. Mark that up as a long difficult day at work.
