Hits to Kill Script

@ Mondays
Try to find the mean hkoing for first Horntail head using any method... it's not easy no matter what you do, any formulas will involve summations and factorials that will get very ugly.

With anything above 100 hits, HP/meanhit is usually the quickest way to get a meaningful answer.

Obviously. It's just a matter of precision. First 20 hits should be able through straight binomial, rest should be done with another formula replacing it because the difference between the answers lower. Then finally, use mean.
