Yeah, I get that.. But my point was that there's no way to determine how much chlorine loss you have without knowing the peak to begin with. You can get a good idea of the peak, assuming no algae problems, by adding your chlorine in the evening and then measuring early in the day before the sun hits the pool. Or add it, let it circulate for a couple of hours, then test....it'll give you at least a ballpark.
