I think that’s the only relevant thing for deciding this sort of figure, otherwise you could pluck any number out of the air.But that would imply that we've got to pay up their contract if they leave (otherwise why hold out for the precise amount we still owe them?). But surely if Stevenage come in for them and pay compensation for them, and they voluntarily choose to join Stevenage, we've not got to pay them anything?
What we're holding out for is in effect a transfer fee, I don't see the relevance of the amount remaining on their contract in deciding that fee.
