Romain does your short ratio box solve the classic MT75 problem of 2nd and 3rd being too far apart???

Ive always found on standard ratios its not easy to do a fast change from 2nd to 3rd when above 5k rpm without burring the synchros.

Can you mix and match ratios to solve the 3rd gear problem yet still have a sensible ratio for 5th gear for road/high speed use??
