you can also expect to pay at least 2 millions if you wanna get a lvl6 trainer with wages below 30k; or you can get one for 1k and pay starting wages of 90k.
you can easily get a lvl4 trainer with 18k wages for 1-5k.
in the case of a player who buys a lvl6 for 1k and 90k wages, in 50 weeks, taking into consideration that the wages of a lvl6 grow exponentially faster than a lvl4 and estimating the average difference of wages in around 80k, that means 4 millionsmore paid in salaries if you have a lvl6! 4 millions! if you buy one lvl6 for 2 millions and 30k salaries, considering an average salary difference of 25k during 50 weeks that makes 3,25 millions! can you add 3,25 millions more in value to your player than a player trained by a lvl4 in this meantime? even if you have 3 players being trained you'll need to add more than 1 million more value to each one of them than the single player trained by a lvl4. just saying.
