Has anyone ever come across an MAB duration longer than 30mS out in the wild?

I currently have some code that works perfectly, but has an issue with an MAB greater than 30ms. I can re-work the code to resolved this "quirk", however it would trigger a domino-effect rewrite and I would rather not do a major rewrite if a 30mS MAB is rare to non-existent.

Thanks for your input!
