With 270 you'll be in the upper tiers for all but Bournemouth I reckon ? It was 234 for Leicester and 248 for Watford so will be similar for most other games (although presumably will rise as peoples points totals rise through the season)
I dunno actually. I am a JCL (4 year ST I think, poss 5) and went to less than half the away games last season, but was almost in the first wave. Our average away attendance can't be much more than say 1500 (maybe less, and with only a core of a few hundred doing most/all games ?) so I'm not...
