I wish they'd just increase the automatic off time to five or ten minutes. I also wish they'd use a method that isn't so finicky to tiny variables and would be more consistent.

Having said that the phosphorous ULR checker does seem to be pretty reliable for me. It uses the same process as the phosphate but measures phosphorous; then you do some simple math to estimate your phosphate concentrations.
