As a postscript to the above, I have calculated a slightly easier way to do it.

As player 1 needs to reach 25 quality points, just add the three columns together, which total 63.6, towards a nneded total of 75 (3x25). This means he needs another 11.4 to reach the required 75, meaning 11x5 plus 2 for the extra 0.4 which equals 57.

I must be getting tired, now even I'm getting confused.
