I just picked up one of these:

Thought it might be a better approach than dumping random amounts of air and going by what 'feels right' after a few practice laps. Maybe not. At least the results will be measurable now.
Got the 60psi version. Turns out my floor pump was about 10psi off! Which is huge!
Weighing in at 190lbs, 32(front)/35(rear) psi feels safe on Clement clinchers. 30 in the front felt like pinch flat territory at about 38 minutes into a race on a rough course. Didn't experiment further with the rear yet.
Should also note that the Clements measure 35mm, not the labeled 33mm.
I really want to get on some tubulars...
