Second day of joining Alpha

Today is still the 16➕2 gear, still brushing BR, but after I finished brushing and checked the balance, I found that the loss was actually more than 1u higher than yesterday, yesterday's loss was only 3.3u. I don't know what went wrong. I brushed 17 times, although it was one more than usual, but the normal loss shouldn't be that high. Shouldn't this be a mistake? #Alpha
