I think the soft spot for lvl 6 trainers is in the 50k area, as you can get some for 200k-300k or so (both my trainers were bought like that: mid 50k salary and around 200k hiring fee (which for the one with career extension is very good). I think you need to take ALL the trainers not just the low salary ones when you calculate.
Also, I think Zajino is right, it would be better to agree on a holding period length and calculate what it means in terms of overall cost to have a clearer picture.
For example. Take a guy with 55k salary and 200k fee. He will cost you: $55k*1.3723*28+$200k=$2.313m over 28 weeks and $55k*1.9655*56+$200k=$6.254m over 56 weeks, where 1.3723 is the average increase over 28 weeks (1 to 1.8235) and 1.9655 is the average increase over 56 weeks (1 to 3.4765).
Assuming you can always replace this guy with a similar guy for the same price, you should roll the player when his overall weekly cost is the lowest. If you do the math for the trainer in the example, you'll find out it is around the 14-15 week mark. So let's say you fire-rehire your trainer every 14 weeks to make it simple: the cost for the period is $55k*1.1603*14+200k=$1.093m which translates into $2.190m every 28 weeks or $4.386m every 56 weeks. This is based on the assumption you fire the coach between the training update and the financial update and buy the replacement between the financial update and the next training update.
Note that this broadly equals to rolling a 78k salary trainer for 1k every week. Any player that costs more than $1.1 million every 14 weeks will be worse than that. I think 80k per week is very good value for money in this period for lvl 6 trainer.
Now let's take your average guy and do the same thing. You get $3.074m for 28 weeks and $4.870m for 56 weeks and there is no way to make these numbers look better by rolling the trainer earlier as the break-even for doing so is around the 55th week. So this trainer is about 500k more expensive than the ones in the example at best and they don't give you the flexibility (for example train stamina or FT with a minimal coach every 14 weeks at the end of the season).
Finally let's examine the internal hiring. They cost $3.344 for 28 weeks and 5.852k for 56 weeks. Now instead of 500k, you're looking at $1.5m more.
Per week, over 56 weeks the example guy costs $78.2k, the average guy costs $87.0k (+9k) and the internal hire costs $104.5k (+26k). This is the real difference: you're better off buying 90k salary trainers for 1k from the list every week than using the internal hire...
