What Kerry and Frank suggest is correct. Frank's suggestion would be the best, in terms of making a copy of the league, at different points in time, then change the rule in the copy, go back to week 1 and forward, making sure the rule is changed, then comparing.
Many years ago, I actually kept and maintained 3 exact copies of a league, to compare the 3 methods of doing team handicap, to show the league needed to get off the stupid team handicap rule of "Difference between team averages". After seeing that there wasn't really any change to the outcome of the season, as well as other benefits I explained, the league changed to sum of bowler handicaps method.
