How to find Halo 2 Highest Level?

My friend claims I reached Level 50 and he reached level 48 in Halo 2. I distinctly remember that this was Halo 3 and we never got close in Halo 2 because the ranking system was actually legit and we never broke 40. SO my question is:

Can I find the highest rank I ever obtained in Halo 2? On the page I can only review individual games. Is there anywhere better to find this?

A legit 40 in Halo 2 was amazing at the game. At 48 and 50, you and your friend would have seen the symbols, not the numbers, and you wouldn’t have forgotten. It was close to impossible to get this without cheating.

play and find out??
