25 pieces of knowledge can be obtained, duplicate knowledge can be obtained.
Only worth going for the guaranteed knowledge when the chance to obtain new knowledge is less than 10%.
This means when you have 2 out of the 25 left to obtain, 2/25 = 8%.
Expected attempts to obtain new knowledge goes up with each one obtained, 25/25 + 25/24 + 25/23 + ... + 25/3.
This sums to be 57.899..., you can then add on the 20 runs needed for the guaranteed knowledge for a total expected amount of runs to be approximately 78 runs.

I think this is the minimum average number of runs that it will take to get all the knowledge. I hope they make it a bit easier, maybe increasing the number of scrolls per run to 2 would already be a great improvement. GL tongue.gif
