Thanks again for this. I'll try 55/65 or so, though because my only high pressure (ie, > 30 psi) gauge is the doubtful one on the pump, I'll have to get another one. The other day the pump gauge said 20-25 for the 51 mm F Freds, but the low pressure gauge showed ~ 15 in front; and indeed it felt soft to my thumb.
Does anyone have a road Presta valve gauge to sell cheap or to trade?
