I had one really new unpaid collection removed. Paid OC several months earlier and disputed online at all three CRAs as paid before debt went to collection. This alone gave me 70 points.
Had one old bad collection account removed. Disputed it online because I didn't know if the debt was valid or mine. CA didn't validate and deleted the information. 11 Points here.
Increased the CL on a dell account reducing UTL from around 74% to 30%. This was 16 points.
