I meant in the last 20 years or so Kentish. The Premier League era, as it was clearly a significant shift in the attitude of the game - the days of a working class game that saw 30,000 on the terraces at HP are long gone, but that applies to almost every ground in the country, except maybe our forward thinking opponents from yesterday.
I'm not in a position to pull out the stats off GoS yet, but I think if you compare like for like from the previous times we were in the 4th tier to now, there's an uplift in core support. Particularly with the 6,500 that regularly saw us get turned over at the arse end of League Two.
I asked on a recent thread about an LDV trophy match against Exeter which had about 1,500 turn up to compare with the current situation of the chekafraud when we had 3,000 odd (?). In the same competition and fixture over the last 20 odd years we've had attendances from 1,500 to 11,000 to 3,000 (during a boycott).
