Deleting late payments from credit report will my score increase

[tnph04]

Just wondering if anyone has been successful in getting some late payments deleted from their credit report.  I am in the process right now of getting 3 negative late payment fees taken off my report.  I don't need a definite answer, just a general idea if my credit score will go up and if so how much.  I know its always hard to predict how much but want an idea of what I can possibly expect. These are almost a year old so not sure how much they might effect my score...
June 2012   90 days
July 2012   120 days
Aug 2012   120 days

This account has been open since 2006 with only these late payments, all current and up to date since Aug 2012

Those are major derogatories so if you got them removed, I would say yes, your score will go up.  Have no clue how much but I would guesstimate around 50+ points.

That's good to know.  I just wasn't sure because they are almost a year old.  I guess any kind of an increase would be good.  Thanks
