I know I am playing a bit of a guessing game with her. I gave the 0.25u for the 151 because I hadn't caught a number that high in the previous 5 days. I still wonder why she was 151? It seemed to work out ok, tho. If she's below 150 and above 130, I will try 0.1u, for sure. But the past 2 days are making me hopeful ;-)
