fast trainers

I'm trying to figure out who is a very fast trainer or not. I don't want those that are just above average lets say those that cost 9mil if average cost 7mil.
But I don't have a clue what the best fast trainers should be costing. I haven't seen any players that cost "a lot" yet on the transfer list.

So anyone know what the expected market value on fast trainers for manager level 6.

Is it true that Nordeus sometimes release fast trainers on server reset?

I had a 55m 19yo ..avg value of a decent high 5 star being 30-40m .. and he was one of the crappiest trainers I ever had. It took two full runs of all three training levels at Hard training to gain 1 point ... that's the most extreme counter example I've seen to the "high value players are fast trainers" mantra. I have no idea how to consistently find fast trainers.

we need a list of prices per level....-.-''
