9th day of joining Alpha

16➕2 Today the loss is about 3.3u, which is a little bit less than before. Today I saw in the comments that someone was刷ing 18➕2 and 20➕2 levels. What kind of刷法 is this? According to this刷法, how much u would be lost in a day? On average, if I can't grab an airdrop for two days, I will be at a loss. I just calculated that if I刷 the current level loss of 3.3, if I刷 18➕2, I would lose 13u in a day?
