Because if will have 3x fitness sessions before the next game, and one group of guys needs to lose 2-3% and another 12% and another 15% then the combinations I can make from doubling some of them means I can calcluate it and do three sessions of training in the hour, rather than need to log in every hour ... which I'm not going to do.
But then, I need to see that they're needing those exact values to calculate those trainings.
