Just thought for a moment that the method of 5*18+10*17 is also a bit incorrect, because on the 12th day you can claim 200 points, and even if you start claiming one airdrop every day from the 12th day, you will still need to claim until the 16th day. Anything beyond 15 days still needs to be compensated by 16+2, so it really depends on the actual situation. If the airdrops are slow, you will still need to claim more 16+2 to maintain the score for claiming airdrops.
