Not such a silly comparison IMO. Attendances across the league are down by about 1,000 per match while Wasps are down by 6,000 per match. That can't simply be put down to the pandemic if other clubs are not seeing attendances drop off quite so sharply. That is a really alarming number.
The % occupancy does leave Wasps looking worse still, and while it is distorted by the size of the stadium, that doesn't make it an altogether irrelevant measure. Compare Sarries, top 2 all season and packed with big international stars, yet consistently failing to fill a 9.6K ground, while Bath, despite their woes on the field, and the Rec's limited facilities, continue to pack them in week in, week out.
% occupancy should be a concern for Wasps. Occupancy of 30.5, as reported, means less than 10K per game, compared with (again, based on the assertion in the article that we've lost 6K per match) 16K pre-Covid. 9.5k rattling around in a 32K stadium isn't fun for anyone. If we've still got the big plans to go with the big ground, then it needs some people in it to generate an atmosphere that will keep people coming back. If that means a return to free/discounted community tickets then so be it, they still add to the atmosphere and of course spend money once they're in. Otherwise we are just like Irish in Reading: soulless.
Shame the article doesn't include the raw data so we can draw our own conclusions and compare how other clubs are fairing rather than just relying on the cherry picked headline stats in the article which don't give the full picture. Those headlines however make pretty poor reading for Wasps.
