How to use Virtual Dyno Properly

I know that this is supposed to represent an uncorrected dj number, my question is as follows:
Would it be logical to say, for comparison sake, that an actual log on a dj with occupant weight of 0lbs will yield a number within +/- 3% of the actual dyno number, and it could be used to compare an accurate road log w/ occupant weight?
I am trying to find what would be the most accurate way for me to compare where I was @ a dyno day to where I am right now with the addition of a few mods and switching to V7.
Thank you for any input.

This is a really nice article on how to use it correctly, i would still go to a dyno though, maybe for people that don't have a dyno near them would be more than awesome to have.

Sea level is 29.9 baro. 5000' elevation is 24.9. The "30" that your local weather tells you is a "corrected" baro reading for weather. Regardless, on VD, to correct for elevation, use the following chart and put the baro for your elevation into the baro box on the VD run.

Okay. But just leave the CF at default, then use the baro to correct for elevation. (When I was talking about 1.2CF being too much, thats for a real dyno. A real dyno is at 1.0 CF default, so when you do a 1.20CF, thats a 20% increase, which is too much. On VD, the "default" CF is 1.09, so using 1.2CF is a 10% increase. Anyways, read below to properly correct for elevation in VD.)
