Expected number of kills isn't very interesting (just do 1/droprate). The other thing you proposed, number of kills to get 50% odds, is very interesting and I like the idea of maybe adding a column for a couple percentiles. Best I can work it out, the equation would be ${\displaystyle kills={\frac {\ln(1-percentile)}{\ln(1-droprate)}}}$. For example, baby mole dropdrate is 1/3000, so you get a 50% chance at ${\displaystyle {\frac {\ln(1-0.5)}{\ln(1-1/3000)}}\approx 2079.09}$ and a 99% chance at ${\displaystyle {\frac {\ln(1-0.99)}{\ln(1-1/3000)}}\approx 13813.2}$. Anyone want to double check my math on this? Riblet15 (talk) 07:59, 1 March 2021 (UTC)
