Sweet! I bet it's nice and sesitive. I like the more sensitive PCs. the less sensitive ones kill the lamps sooner since they lead to longer burning times.

Yes same here,I like the more sensitive ones,this one is more sensitive.

How much earlier would this come on over a 1.5 candlefoot setting or a 2.6cft setting?

I would estimate this would come on about 5 mintues later than a 1.5 cf PC or about 10 or so minutes later than a 2.6 cf PC.

ahh. Here National Grid uses FPolc Sun-Tech PCs that are VERY sensitve. FP seems to have layed off their quality control workers though since there are quite a few of them here that are dayburners though (coincidentally they're all 250W HPS lights too)
