Differences in Score and Percentiles B/T MGMAT and G-Prep

Hi, my question is two-fold.

First, does the GMAT first score V and Q, then assign the percentile ranking, or vice versa? Secondly, I got a 680 on my first GMAT Prep test, which it ranked as 85th percentile. On the MGMAT test I took a few days earlier, I got a 670, which ranked in the 89th percentile. The GMAT Prep scores line up exactly with the percentiles that MBA.com lists here: http://www.mba.com/the-gmat/gmat-scores ... means.aspx.

So I'm wondering...would my 670 (89th percentile according to MGMAT) have been more like a 690-700 for the actual GMAT? But, that doesn't line up with what I've read, that MGMAT's algorithm might be inflating scores 10-20 points right now.

We're changing it tomorrow, actually. :) The real test updated their score-to-percentile charts earlier this month (and of course they updated GMATPrep at the same time). We had to do some additional calibrations, so it took us longer to update, but the scores will be updated as of tomorrow (30 Aug) at noon eastern. We'll be posting instructions in your student center about how to convert any old scores (before 12p on 30 Aug) to the new percentile charts.
