I have ourchased more then one report here as the result of my True Credit score chaninging only to find out that there was no change in my FICO score.
I supose if you just got a 30 day late your FAKO and FICO score would both go down but I still say its a mute point since FAKO scores are not used as far as I know with any lenders.
As Haulings says known changes in your credit report is whats really important here. The scores will take care of themselves and as always they are what they are.
I use EQ's credit monitoring system since it also montiors changes in my EQ FICO score.
