While this is a cool comparison, there are some obvious questions.
1. Do you have the surface the same on all 3 ? I believe abralon did not exist back in 1997 and back then, a lot of high end stuff came at around 600 grit from the factory. If you took that Fugitive to 500 or the 3D all the way up to 2000; it would possibly out hook that 3D by a decent amount.
2. Core technology from a symmetric standpoint is not that different in reality. While core shapes have changed over the years; a 2.55 RG is still 2.55 and 2.48 is still 2.48. The difference in core tech is more on the asymmetric side. While the 3D and 503C are asyms, as you mentioned, the intermediate diff is so low they are still considered symmetric. So the biggest difference has to come in the form of coverstock technology.
3. With your lower rev rate; you wont see as big a difference as someone with a 500 rev rate. Secondly, even on the broken down house shot; you are still relying on the driest part of the lane to do the comparison which will bring the ball reactions closer together.
To make this a true comparison; bring all those balls with the surfaces at a level like 2000 and throw them on a fresher condition. I am looking forward to part 2 though and see what it shows.
