I have played Rebellion for years and just recently decided to use RebEd to change up the experience a little. I've looked through the forums and have run across a few discussion on editing characters but nothing that quite answers what I'm looking for. Without any changes, Luke starts out with a 75 diplomacy rating. If I edit Luke and change his base using RebEd 10 points from 50 to 60 his diplomacy starts at 90. If I change only the variance and raise it from 0 to 10 leaving the base at 50 his diplomacy starts at 76. Now when editing Vader a 10 point increase in his diplomacy from 40 to 50 raises his diplomacy from 88 to 110. A 1 point only increase in variance with no change to base has no effect on Vader's diplomacy leaving it at 88. Therefore, my questions are what is the difference in Base and Variance and is there a formula to determine the ratios?
