Using your spreadsheet with your assumptions I am getting:
4 CIM traction limit at 17.8 fps
6 CIM traction limit at 26.5 fps
Are you sure you're not looking at the average speed over distance fields from your spreadsheet? Those actually come close to matching your claims.
For reference, from my own spreadsheet I get:
4 CIM traction limit at 16.4 fps actual speed
6 CIM traction limit at 25 fps actual speed
