I'm not sure. We do around 20 away each season, never all of them, with cup games incl probably miss about 5 aways. Often midweek with work commitments, so somewhere between 50-100 points a season short. Over the rolling 4 year period that's approx 300 points average below the top tier but I'd argue that with a decent job, I couldn't be much more committed. It means for Wrexham we got in with our 1850 & 1880 point accounts. If 25% had gone to a ballot, I think we could've easily missed out and of course on a personal level I'd deem that unfair.
There's no perfect situation of course that suits everyone but, with the exception of the issue on kids and some buying tickets with no intention of attending, then I think ours are pretty fair.
