I would be keen to see you run some similar tests where you go by 5 psi over your current 55-60psi, then another 5 psi etc, perhaps stopping when you are 10 psi below the tyre pressure you had with the Continental GP4000II's.
This is a good suggestion! I used some charts (I think from a Jan Heine article) to get a ballpark for the 32mm tires at my weight (about 80kg bike+rider). Mostly it’s just based on feel and a WAG!
I’ll certainly try increases and decreases in pressure to see the effect.
