The away count would include hospitality and board members etc. too. They still get a ticket, even though they don't pay for it. It still gets added to teh matchday count. I counted 50 in the away section and it's not inconceivable that there were 30 in the directors box to do with hospitality/directors/sponsorship/backroom staff.
But when Macc brought down 35 or wahtever, you could actually count 35, unless they didnt bring any hospitality fans etc?
