Ok, assuming a weekly increase of 2.75% per week, these are the break even points that I calculated, assuming you are trying to replace your current level 7 with another level 7:
(there was some rounding involved)
Assuming the new trainer has a $30,000 salary
Bonus of new trainer = $5 million, keep current trainer until salary = $173,200
Bonus of new trainer = $4 million, keep current trainer until salary = $155,000
Bonus of new trainer = $2.5 million, keep current trainer until salary = $125,000
Assuming the new trainer has a $20,000 salary
Bonus of new trainer = $5 million, keep current trainer until salary = $132,500
Bonus of new trainer = $4 million, keep current trainer until salary = $117,250
Bonus of new trainer = $2.5 million, keep current trainer until salary = $92,500
Is an extra pop per season (over a level 5 trainer) really worth that much money? And seriously, if you are not a division I team, why would you even bother?
