any way to calculate watt difference between tire pressures?

A light bike doesn't replace good fitness.

went out for the tuesday eve group ride, and had a bit more difficulty than usual.

got back home and realized my tires were about 30 psi under inflated @60 per wheel, instead of 90-ish

Seems to depend on the sate of your local roads. When I'm in the UK I run wider, lower pressure tires than I do when I'm in China for example. I even ran different pressures on Gran Canaria and Tenerife.
