Yesterday I tested the doodad miss chance and I modified the map so I could test high ground miss chance as well as adding much more interactions so I could have a larger sample size. Here are the results.

Hits: 91142
Misses: 80154
Total Shots: 171296

Hit %: 91142 / 171296 = 53.207313656%
Miss %: 80154 / 171296 = 46.792686344%

This time I got even closer to the expected value which is expected with the much larger sample size. Adding more interactions wasn't quite as simple as just copying the triggers and I was worried that the game wouldn't accurately keep track of everything but it seems that it did.
