Can't really make too much of a judgement about attendances from just five games and especially when the opposition has been from the South every time!
The best comparison is with the respective game last season:
Team ..... Attendance 2005/06 ..... Attendance 2004/05
Canvey Island ... 1012 ... 1249
Exeter ... 1312 ... 1464
Woking ... 959* ... 2004
Crawley ... 1365 ... 1270
Aldershot ... 1142 ... 1272
The one huge difference is the Woking game, but that was played at 1pm before the England game. For the rest, we are averaging 1208 vs. 1314 last season in the respective games. It's a drop of just 8%, no more.
If Stanley keep winning, they will easily cover that shortfall; if they reach the 1st round of the FA Cup, they will easily cover that shortfall; and if they built the Clayton End roof they'll cover that shortfall
