I went from azeo to max and lost between 70 and 85 points.
Did you only have 1 card? If so, your individual card utilization is your aggregate utilization. If that's the case, it's definitely possible to lose that much. The qualifiers in the original post of this thread though stated that aggregate utilization needed to stay ideal, so a single-digit number both before/after the individual card max-out. This doesn't sound to be the case in your example above.
I have three.
What was your before/after aggregate utilization then, as that tells a greater story than a single maxed-out card.
me thinks this will be a long session of pulling teeth... better get some popcorn...
