There is one point that gunplumber illuded to, but didn't expand upon.

There is no guarantee that with your AI, the best accuracy will occur at or near the top end. Take for instance the .280 Remington vs the .280 Remington AI. The velocity improvement comparing identical Barrel lengths, and powder type/brand is about 3.5%, or about 100 fps from 2700- 2800 with a 160 gr bullet. It varies changing bullet weights of course and powders, it the 3.5% mostly holds.

But how often do we get the most accurate load near the max? It does happen, but not frequently. You could make the case then at least the AI gives you more velocity potential to find that accuracy node, and it may well be higher than the standard cartridge.
