Players
I know that wages are related to the skills of the players but what about rounding them. I don't find it so realistic to pay a player $5.472. I could pay him $5.500... This way, in economy we won't have a balance of $538.052 but just $538.000 which is by far more realistic... Also, the TV contracts can be rounded. About Atendance and Merchandise leave them as they are (many fans buy just a pair of socks which cost $5.99 or sumthing)
This is possible, and might make sense, especially for player contracts.
Staff
I agree about staff weekly raises but not that much... I also agree with the staff improvement. You could round staff wages too. e.g. This week's salary $15.000, Next week's salary $15.100
This wouldn't be very useful, given that we have weekly staff salary raises.
