Did you know the collection was coming? Sounds like you have a lot of old issues that you are clearing up. Congrats for cleaning it up it is hard work. I noticed I did around the same thing that you did back in feb, my ex and tu has soared, however, my eq took a 25 point dive and has come back up 23 points within 45 days of the deletions.
Recently I paid some cc's down to where it was over 90% util to under 10-25% ind and 25% overall. I noticed this is the best way to see a boost in score most contributors agree. I'm still waiting for the bureaus to update only one card has updated to all bureaus. I have a baseline as of 4/28 so I will keep all updated as to those increases soon.
Good Luck and don't worry if there is a slight drop due to the lost of hx like me it will rebound as long as you get no more no no's to contend with and pay your other accounts on time every month.
