The wait goes on ...

As far as I can see. last season Tranmere had 3 wins 4 draws. From last 9 games.
Wimbledon 1 win 5 draws from last 9
Didn't Tranmere get promoted twice in last 3 year?

The margin of error calculation is not based on the last 9 games results exactly. It's based on how those results ppg compare with the ppg for games up to that point. For example if, over the last 3 seasons your ppg over the last 9 games was possibly not great but, say 1.5 times as good as the rest of the season then Hartlepool would argue that the ppg calculation for the rest of this season should include a margin for error addition to make the ppg for the remaining games effectively 1.5 times what it has been for the games so far

It's all based on the premise that some teams, over the last 3 years anyway, have done better in the last 9 games, or so, than they did in the rest of the season and that it is reasonable to presume that they would do the same this season. There are probably a few hundred other variables you could add to the mix if that still doesn't help your cause

What does this line mean then?

There is then applied to the table the statistical average actual margin for error over the last 3 years (being +6.3 or – 5.45%);
