Having seen the blogger's method of farming Alpha, I am now ready to use the second method to farm.
Every day 16+2, for 15 days 15*18=270, claim 5 airdrops, wear and tear 15*3.5=52.5
5 days 16+2, 10 days 15+2, 5*18+10*17=260, claim 5 airdrops, wear and tear 5*3.5+10*1.7=34.5
Both methods involve claiming 5 airdrops, but the latter method has slightly less wear and tear.
I also calculated the first method mentioned by the blogger; 5*19+10*18=275, claim 6 airdrops, wear and tear 5*6.8+10*3.5=69.
If we calculate each airdrop at 40U, the profit is 6*40-69=171.
In comparison, the profit from the second method is 5*40-34.5=165.5, which is about 5.5U more, but the temptation is not great, so I still plan to use the second method.
However, the probability of claiming high points and big rewards with the first method will be slightly greater than the second method, because after farming for 10 days, the points from the first method will exceed those from the second method by more than 10 points, and the advantage of high scores is still very obvious.
