One line I found interesting...
'The income (and expenses – see part C(1)(k)) of non-football operations only needs to be excluded from the calculation of relevant income if it is clearly and exclusively not related to the activities, locations or brand of the football club, in which case it must be excluded.'
That would suggest that the majority (but not all) of all activity at the Ricoh complex could be included as 'revenue', especially if it utilises the club name/branding.
