That's total matchday ticket income, this thread is about increased matchday ticket prices. There are c. 23,000 ST, c. 3000 away already factored in, so the increased prices relate to c. 4000 seats max x say £8 increase = 32,000 extra revenue per match.
*all figures approx.
£32k minus VAT = £26,666 x 19 = £506,666.
