It is important to distinguish between the material's surface properties and the actual ball surface preparation. Softness, porosity and probably molecular structure are things that are innate to the material. This does basically not change but defines traction. On the other side or as another factor, you add some surface finish to that like polish, an open sanded surface or a rubbing compound on top of that. This greatly affects where the ball does what on the lane, and surely also affects the ball's footprint on the lane.
Wear and oil absorption are further factors, but let's blend them out.
Anyway, I found OOB finishes hard to restore, even if I follow preparation sequences and original polishes and the like. Hence, applying a self-made finish even before you punch any holes into a ball or throw it the 1st time is IMHO a sound strategy, since you get a true reaction benchmark and a replicable finish this way.
