I'll take a guess...
Based on what you posted, you have 5 CCs with a balance of $1475 on a total CL of $2250. Your overall util is 65.6%. If you pay down your CCs to what you stated, and your CR reflects that, then your overall util drops to 32.2% with total balances at $725.
Assuming your overall util was at 65.5% and it lowers to 32.2%, and if it reports that, and if you have no other accounts that can be factored into CC util like a LOC, HELOC, or other CCs including CO'd or closed CCs w/ a balance, and if util is listed in the top one or two slots for neg. items hurting your FICO, and if these scores came from myFICO, then I'd guess an increase of 25 to 35 on EQ and 20 to 25 on TU.
If overall util dropped to under 10%, and at least 3 of your 5 CCs hit $0, then my guess would be 55-65 on EQ and 45-55 on TU.
Just a guess. YMMV.
From your post and ignoring possible Marty math error, I see 1475/2250 65% util with several cards with high util.
From a CC util standpoint I think you could get over 600 if you reduce the # of CC reporting a balance and pay down the debt as much as you can.
IMHO with your plan I think you can get close and possibly to 600. I'm pulling for ya.
I call 18-23 points.....
