Experian 8.0 Increase but big Experian 2.0 Drop

[Anonymous]

Trying to get my head around this one - since I last ran my scores on myfico a week ago, I have had a 48 point drop on my Experian 2.0 score compared to just a week ago - this dispite the fact that the Ex 8.0 score actually increased by 1 point!  All of the other bureau scores are pretty consistent from last week.  

The only big change between this week and last was a paydown on credit cards - currently credit utilization is overall 40% and no card higher than 60% (working on paying that one down). No negatives, lates, inquiries, etc.  Any thoughts on what could have caused this big drop?

That's interesting. My first thought was just a different setup between both made a difference in how it reflected, but that difference is kind of big.

Yeah the timing definitely sucks since I was literally getting ready go for a mortgage pre-approval this week.  This has led to a change of plans and a delay in going for a pre-approval so that I can make the payments to get my overall utilization down to below 30%.  I am hoping I can get a rebound by doing that.  

I know the best approach is to get all revolving accounts below 30% utilization, but for the purposes of Ex 2.0 - does the math work out to get overall revolving utilization below 30% with a few individual accounts above 30%?  Could I realistically see a 20 point increase with that action?
