For me it matters none if it is shiny or dull... the differential creates flare. My Total NV is shiny and flares more than a Dull Danger Zone by far.

This doesn't mean that it won't affect the flare of your bowling ball. When talking about flare potentials and the difference in a dull and a polished ball, do not compare different balls. That's like apples and oranges.

Go to a heavily oiled shot, Throw your total NV at a 1000 grit with say 2 coats of Brunswick high Gloss gritless polish 4 sides. Than throw it at a 1000 grit dull. Or even use it at 4000 grit and than at 500 grit. Even though it may flare more than the Danger Zone, that would be created by the core and the motion you impart on the ball.

But using that same energy on the same ball with a different surface prep, to my knowledge, will result in a change of flare. This would be because the ball is seeing different amounts of friction. When a ball see's more friction it is going to start to make it's turn earlier, when compared to the same ball at a higher grit. Even though the RG and Differential is the same, the amount of friction the ball is seeing throughout the lane changes.

Differential itself doesn't actually "create" flare. Flare is created by the leverage you impart on the bowling ball. The energy you transfer to the bowling ball allows the "pieces" of the ball to go from static to dynamic. Once a ball is rotating and using energy that has been transferred from you, RG differential is a factor on a ball's flare "Potential". It doesn't actually "Create" flare. But it is a factor in determining how much a ball can flare.

I'm going to side track here for a second and move on to deadbait's post. Depending on your PAP deadbait, those two layouts could actually have a fairly similar track flare potential. If you were to try a ball at 0 inches from PAP, and the same ball at 3 3/8 inches Pin-Pap distance,  guarantee you see a difference in flair, and especially where the ball begins to flare.

To your original question.

I'm not quite sure I understand how it is worded but i will do my best interpreting it and giving you an answer to the best of my abilities. I am not Mo Pinel, hehe.

Let's go step by step here as o how I see what you are asking.

A ball has different flare potentials based on different pin lengths to the PAP because of the core's stability, or instability for that matter. A ball with a pin at 0inches to PAP or 6 3/4 should flare very little to none because the core is stable throughout it's roll down the lane, assuming ofcourse you release it correctly.

Now the same ball with the pin 3 3/8 inches to PAP should reach full flare potential because that should be maximum instability for the ball.

From what I get out of your question you are asking if a ball with a pin distance of 3 3/8 to pap, will that flare 1/3 more than a ball that is 4.5 to pap.
And you are asking this because you flare potential is different, but because when moving the pin you change the RG and how long the ball will tend to go before it rolls up, does this necessarily change the flare potential of the ball?

I would think that the flare potential would remain the same because the Pin distance from PAP still dictates the core's stability or lack thereof which is what creates flare. But I would tend to think that the distance on the lane where the ball begins to "rev-up" would change because the RG has changed. i still think that the flare potential remains the same, regardless of the RG change because the core's amount of stability should remain the same. That's just my reasoning, I'd be interested in hearing others thoughts about this topic.
