What’s your point? The club would make more money in the Champions League but getting there ain’t so easy.
I’m also not sure your sums add up, looking at the club’s accounts, the revenue from ticket income was £914k last season (in League One) and £1.01 million the year before (possibly helped by being in the play-offs?). Last time we were in League Two, the accounts showed £936k back in 2014.
