Bill, with all due respect, you've been showing this same video for 10-15 years on here. Every time, people think you hit it rail first, and you end up arguing with everyone. Even Incardona from the best of my recollection when you showed it on the onepocket.org forum thought you hit it rail first. (or might have been here, he's a member on both I believe).
The 2 thin carom table shots you showed from 1992 were not even close to the same. The OB banked at a sharp angle (using pool, not carom terminology). It didn't go anywhere near the corner which would have been 90deg if it did.
The latest video you showed on a pool table of a thin cut "far away from the rail" doesn't look like it was even close to 90 degree.
All you had to do to put this all to rest was recreate your first pool video with the 3 shots on it, but with the OB a solid ball width away from the rail, and the CB at a recognizable spot that is easy to verify its 90deg. People have been asking for that for 15 years, and you never provide it, just argue more.
