You are absolutely correct, which is why I asked the question. I was hoping other people had noticed this, which it turned out they did. I'm just late to the party.

If I was trying to verify an issue with my corner of the game, you are correct. If the problem is universal, a broader dataset is required. Fortunately, other people have already done that, so I can compare my results to theirs to disprove my theory. Thanks again for your input and helping point me in the right direction!

That dataset is only valid if everyone ran the same hero and powersets and on the same hardware/software config as me, but Bopper already linked me to the info I was looking for. Thanks for your advice here. Much appreciated!

Thank you, @Bopper! This is exactly the info I was looking for and I'm happy to see that I'm not the only person who thought RNG may have been biased. If I had an inspiration to give you, I would.

Interesting suggestion. Won't the combat logs eventually get purged, though?

I've been tracking it, but wanted to find out if other people have seen this before investing the time. After all, one person doing something 500-1000 times is a rather small data set. If other people are seeing this, we can pool our research to see if this really is a universal issue or not. Want to help me prove/disprove the theory?

I'm pretty sure to hit rolls are higher than average. My main toon is a high level Grav/Kin Controller, which means that hitting things is key to his survivability, and I've made sure his final to hit is clamped at 95%*, even against high level mobs. Thus, I should only be missing 1 out of 20 times, but I'm seeing about twice that against all mobs at all different levels. Additionally, I have a low level Stalker and have been seeing the same thing there, so I think this is a universal problem and is not limited to hero/villain or a specific class or power set. However, I don't have the time to check every possible permutation. Can anyone else confirm if they are seeing this problem? * For the record, I know how to calculate the final to hit using Accuracy and ToHit mods, and the numbers in the combat log check out. The problem seems to be with the raw to hit roll.
