Judging by the empty seats in the East against Wolves I reckon there’s at least 500-700 less STH in that stand. Couldn’t comment on the West as its hard to tell when your sat in there.
You could give it an educated guess on that Wolves gate. They brought about 4,500 that leaves app 12,000. You can say that there’ always around 1000-2,000 floaters for a home match depending on who we play. Therefore I would say we’ve anything between 10,000 -, 11,000 STH max.
I’m afraid we have too many of these:-

I agree, eh well not to worry, dropping kids off at me mams, then pub then dw, :D
