Well I make that to mean your entire wages for those players over the season will work out at 642.6M a season (Simply add up all the values of the contract wages to get the total).
Day 1 you don't pay wages, but do for the next 27.
Thus 642.6 divided by 27 should = your daily wage cost.
I make 642.6 divided by 27 to be 23.8M per day - that should be your daily outgoings on wages.
Your wage outgoings compared to other payments just isn't matching. The only other thing to consider is if you have renewed contracts with players then their sign on bonus will go in there - but even still, your daily wage outgoing for today isn't matching what it should be, unless you have had a new player go in/out today which distorts things.
