4. Conclusion

1. The profit margin of 17 points * 15 days is the highest;

5. The profit amount of 18 points * 15 days is the highest;

12. The profit margin and profit amount of 19 points * 15 days for a certain 6 days with 1 extra point are the lowest;

The first choice is 17 points * 15 days, the second choice is 18 points * 15 days, and to be safe, choose 1 extra point for some 5 days in each tier, after all, choosing the basics is the way to go, reductions may or may not happen.

The above is just theoretical data; in reality, if you grab one more airdrop, it could be hundreds or even thousands of U in profit.
