Question on Drop Rate

actually we are closer to a solution than we thought

tests			additive	mult	add expected drop	add 1.96	mult expected rop	mult 1.96	diff in means	sum of CI 95 range	min tests
fam and pendant	1.6	1.2	1.8	1.92	72.35	16.11	77.17	16.60	4.82	32.72	46.01
card/event pendant	2	1.2	2.2	2.4	88.42	17.67	96.46	18.39	8.04	36.06	20.12
card/event fam	2	1.6	2.6	3.2	104.50	19.06	128.62	20.89	24.12	39.95	2.74
straat pendant fam	3	1.6	3.6	4.8	144.69	21.97	192.93	24.72	48.23	46.69	0.94
straat pendant card	3	2	4	6	160.77	22.96	241.16	26.89	80.39	49.86	0.38

based on drop rate extrapolated from straatlamp and zapta's tests.

problem we have faced is the variation in the drops

so I have calculated the number of runs you need to do to overcome it, to basically have it such that the result is clearly one or the other
based on a 95% confidence interval. I have calculated how many tests you need to do so that the 95% CI do not overlap. when that happens the result is clearly one or the other.
maybe do a few more than the listed min number to be sure

bascially straat can do it in one run or two runs since he has so many equips getting 200%, so it produces a large enough difference
