I don't know about the re-bucket. When we first started working on my fiance's credit, there was 1 judgment and 2 collection accounts on the credit report. We disputed the judgment and it was removed. My fiance's FICO scored dropped from 677 to 666! At the time we assumed the bucket theory.
The other 2 collections recently came off, but in the meantime a third was added in early November. He lost like 20 points or something from the new collection, but since then the other 2 collections have come off w/ a loss of 3 more points. What the *bleep*?
It's frustrating sending all the GWs, disputing, and doing the f-u phone calls only to see points lost rather than gained.
