The Tranmere statement is a bit cack handed. At the beginning it does indeed state +6.3% or - 5.45% (suggests an either/or result) which makes no sense. later on it states - 5.45% to +6.3% which suggests a range of results. I'm guessing that this means that, over a 3 year average, the difference in teams' ppg performances, over the last 9 games of those seasons, range from being 5.45% worse than in the earlier games to being 6.3% better than in those earlier games. Each team's adjustment would be somewhere in that range
