Both my TU and EQ scores plummeted when Alliant Credit Union reported
my little $500 "share secured" loan as paid off.
EQ went from 722 to 693.
TU went from 733 to 708.
Wow.

Long term AAoA and increasing age of youngest account will add major stability to score fluctuations, so factor that into your strategy.
Well the thing I was testing, which was whether the imbalance between the TU & EQ scores on one hand and the EX score on the other, would be corrected if all 3 showed the same data for the share secured loan..... was successfully tested. Because now that all 3 bureaus show a zero balance, the 3 scores are in balance.... In fact EQ fell to the exact same number as EX. (TU is understandably a bit higher than the other 2 for the unrelated reason that it shows 1 old public record while each of the others shows 2).
So mission accomplished as far as that goes.
(Of course I didn't expect to take that big a hit, or I would have foregone my little experiment, or as you suggest, just waited it out until the mistakes were corrected in time.)
So now I have a new mission, but this one isn't diagnostic and is much less cerebral. It's just to get those points back 
I'm tackling that mission by taking out another $500 reindeer game loan; paying it down to $90; removing autopay from the loan; and paying about $2 a month for the next 48 months (or until I'm ready to risk another point drop for educational purposes).
I took a 15-17 point loss when I paid off my secured loan at NFCU in December. I also had 3 new inquiries so that might have made a slight change.
Early January I took out another secure loan. I have paid off 60% so far and will pay another 20% in March. Then I will make small payments for the rest of the term. I can't wait to get those points back.

Onward and upward
