Yes, I'm 100% sure that our home attendance is diminished by our current capacity.
The second part could be answered with a simple straight line calculation, and I'll provide it below:
Championship average away following 1,696
Oxford United average away following 1,453
Oxford United following as % of Championship following 85.67%
Championship average home attendance 21,896
21,896 x 85.67% = 16,071
There are lots of possible caveats to this, such as the fact that it's natural to expect demand to be higher in our first season back at this level. To counter that we, as a fanbase, are used to winning, and this season we have not been doing that. Furthermore, our away form has been poor, and the results bad (I have only travelled home happy once this season, so far!), so that could be a negative factor. There are new grounds for many, so another positive, and a further one is that we are fairly centrally located, so away grounds are easier to get to than from Plymouth or Sunderland, for example.
16,071 is not at all a crazy figure for us though, as I've said all along when involved in the stadium planning. It was why I felt 18,000 was the optimum capacity and that 16,000 is too small, because don't forget, we also have the new stadium uplift to add in.
Anyway, when we move, what are those extra 71 people going to do when they can't get into The Triangle???!!!
