Excellent work elvra. Your logic is kinda all over the place. I assume you are referring to the N equation for determining number of samples to take.

n= ((sigma*z)/E)^2

where sigma is the st. deviation (found in excel)
z is the confidence level (1 is like 66% and 1.8 is like 95%)
E is the acceptable error
n is the number of samples.

now since we know n in your case (number of aggy kills) we can see what your error was since we also can pick a z value and we could calculate your standard deviation. And like elvra said (I trust his calculations, I won't redo them) your error is probably big enough to account for all the variation you see.

Aggragoth drop is unfair for druids! although there might be more druid drops. In general there needs to be a lot of druids to do Aggragoth, thus making the change of a druid to actually get an item smaller than the likelihood for rangers, as there normally is a limited number of rouges/warriors/rangers.

Isn't this due to the amount of people that use a particular class? There aren't that many Rangers on Sulis so maybe that's why?

No because there are fewer druids than rangers

Cool there's a branch of mathematics devoted solely to CH? Awesome!
