Title: What is the difference in tracks ?
Post by: X-MAN on March 13, 2004, 05:25:05 PM

I hear about High, Medium and Low tracks all the time but what defines them.  How close to the fingers and thumb is considered a high track, medium track and low track ??

according to TRacks drill sheets for the animal:

over 5-1/4 = high
under 4-3/8 = low

in between = med.

I'm not sure as to what this means...is this in relation to the fingers/thumbholes?  Explanation please, thanks much!!

I believe that the distance is the horizontal measurement that is used to find ones PAP.  My PAP is roughly 5 and 1/2" right from my grip centerline, so I fit into the High track group according to Tracks drilling sheets. Check my profile for other technical aspects of my track.

in theory that makes sense, but...

wouldn't a high-tracker (like myself) track closer to the thumbhole, or even track over the thumbhole, whereas a low-tracker (PDW for instance) would track further away from the thumbhole?  In that case wouldn't a low-tracker have a track further away from the PAP?  Or am I sadly mistaken?

There is a lot of information on this site as well, you may be familiar with it.

loose5682 -- Your PAP is the point on the positive side of the ball that is equidistant from all points on your (first oil ring) track.  The PAP numerical components, horizontal and vertical, are measured by drawing a line perpendicular to the grip center line through the grip center (this line is called the grip midline) and then a line perpendicular to the midline through the PAP (either up or down), and measuring the two components.  So as the track gets lower (further away from the thumb and fingers), the horizontal component of the PAP measurement also gets lower (ie., the PAP moves closer to your grip center).  
You are correct that a low track is further from the PAP than a high track, but that's not how the PAP components are determined.  --  JohnP

I was not concerned about PAP measurement when I started this topic.  I know what part they play.  What I want to know is what guide lines to follow if to find out if one has a high track, medium or low track on the ball ??

Hey Andrew,

Just imagine it this way, the lower your track, the smaller the number is for your PAP.  The higher the track, the higher the number.  ie, A person with 5 1/2 PAP is know to throw a high track where as a person who's PAP is 4 is considered to have a lower track.  

John, I'm sorry, trying to understand the lower track farther from pap statement?  His pap would be simlpy closer to grip center then a higher track player but how does that make it further away....further away from who's pap?  Sorry, confused here...

tenpinspro -- Take it to a ridiculous extreme and say the ball is spinning on one point (which would be the NAP) and sliding down the lane.  Now the distance from the track to the PAP would be half the circumference of the ball, or 13.5 inches.  As the track gets higher its diameter gets larger and any point on the track is closer to the PAP than for a lower track.  A track that is really high is about an inch from the grip center and the grip center is about 5 1/2 inches from the PAP for a track to PAP distance of about 6 1/2 inches.  See how it works?  --  JohnP

Thanks John,

Never thought of it that way, then a bowler who hypothetically tracks completely on the bottom side of the ball(Asian spinners are close), would then have their pap say somewhere near our cg, correct?  Therefore, the track distance is much further then any high track rolling ball....did I get it John?  Is this what your trying to explain?  Thanks again....

Rick -- You got it.  It's amazing how hard it is to explain something in prose that would take about 30 seconds if I could show you on a ball.  --  JohnP

Added on edit:  I reread your post, and you said that for a "helicopter release" the PAP would be near the cg.  I think you meant to say it would be near the gc (grip center), and if so that's true.  It would not necessarily be near the cg, that would depend on the layout.  Also, the track to PAP distance has no significance or use in layouts that I'm aware of, I was just trying to be sure the original poster understood my explanation.
