The numbers I used are typical of the differences between a 15 and 14, some times they will increase and sometimes they will decrease.

Yes they are different for all weights. Each manufacturer does things a little differently. For Track, we use the same weight in filler and shell which when we decrease in core weight, it raises the rg and alters the differential.
For me personally, I see a tremendous amount of difference in a ball that is 2.50 and 2.53 rg. My personal magic number has been 2.50 to see a ball naturally rev up off my hand without having to hit it where as a 2.53 will lope down the lane and not rev as much. Having that much differnce for me creates a different breakpoint down lane and changes how I would have to play the lane.
If you look at Roto Grip, their numbers are completely different sometimes for a 16 to 15 and then 14. It is apparent they are designing balls to 15lbs which is still the most popular weight sold in high end performance.
I've been throwing 14lbs for 4-5 years now, if there are any balls that you are interested in, let me know and I'll dig up the rg's and diffs for you if you want. Thanks...

Does Track change the weight of their balls by raising or decreasing the weight of the core?........or by changing the amount of filler in the ball or thinner shell surface, or how?

Set your Windows to Chinese and this would've came up...
..lolLow rg balls are created by wrapping a lighter material around a core which then makes the ball "core" heavy or "center" heavy which allows the core to spin faster or defines it as "early" revving.
High rg balls are designed by wrapping heavier material around the core which then makes the outside portion of the ball heavier causing it to lope down lane some which defines it as "late" revving.
If you look at specs from 3 different weights from 14, 15 to 16. You will notice that the rg's increase as our overall weight drops which tells me they are keeping one constant (filler and shell) while decreasing the weight of the weight block, making the outside "proportionately" heavier in ratio based on my explanation above for high rg balls.
If the rg's on a 14 were lower than a 15, then that means they have lightened the weight of the surrounding material on the ball while keeping the weight block the same weight.
Hope this makes sense Unc or feel free to pm me and I'll give you the rest of the novel....
Don't forget to set it on Chinese though....--------------------
