Guard medium clue drop rate too high

[Fexbot]

🐛 Bug Report

With the medium Falador diary and medium combat achievements completed the medium clue drop rate should be 1/100. I killed 5508 guards and received 127 medium clue scrolls (which is an average droprate of around 1/43). The probability of getting 127 or more clues in this amount of kills if the drop rate really was 1/100 is less than 10^(-16).

I hypothesize that the issue is related to the Falador medium diary, but I'm not sure.

Diary doesn't do anything, base drop rate is 1/106 even without it. Were all those trips ran in the past 2 days (since last bot reset)? Drop rate seems fine here
