Reached data analysis limit time inconsistent

After the limited amount of free questions for 4o, I, like everyone else get the “limit notification”. The only problem is that every in every attempted chat after the limit is reached, it shows a different time for when it’s possible to try again for advanced conversation.
On top of that, the time seems random and I never know when I can try again.

Does anyone know what’s going on here?

Thanks!
