For a single Avalon 741, after 3.5 days, shouldn't it be at the peak average for the 5nd? Also, what should be the average?
It may take a bit longer...patience. I run a total of 3 741s (one in Labrador, and two here at home). All of them average 7.5TH or better at the pool. They'll read, generally, a bit over 8TH via the Luci, though.
