Wrong, on the day of the airdrop, 15+17 points were deducted, and when the airdrop was removed that day, the points would go up.

Infer, if you maintain brushing 17 points every day for 15 days, you will have 255 points. After 15 days, if you brush 17 points and then deduct 17 points, the score remains unchanged. If you claim 5 airdrops, you will still have 180 points. Given that the minimum requirement for each airdrop is 195 points, after reaching 180 points, if you continue to brush 17 points and deduct 17 points, you will still have 180 points. Following this pattern every day, doesn't it just enter a deadlock?
