The 13T difference is probably because sram can't seem to make decent shifting ramps for their chain rings. There are many complaints about chain drops in both directions, blamed on the FD, but both of my bikes with not-sram cranks work great. It makes no sense at all to design a 12 speed drivetrain to gain additional range, then take it away by not offering any cranks with a 16T difference. When I made the change to force axs, I was already using Campy 12 speed mechanical with a 48/32, but the new 10-36 cassette offered more range than the Campy 11-34.

I now have the same low gear as SRAM's wide 43/30 and more top gear with the 46 big ring. Makes sense to me. I've never read any sensible explanation for SRAM's chain ring limitation.
