How to identify fast trainer in the transfer market and through training?

[talisman]

I have skim read the topic, and one thing that I would like to seek clarification is the Training Factor (Value/Wage):

It's entirely possible to inflate that number by training the player, increase market value, keep the wage constant, and put the player on the market? Is there a way to distinguish which player has a pure high Training Factor?

Identifying fast trainers only works for the initial purchase from the TM of a Nordgen, as identified by k1tb. Once signed, the Market Value changes, as does the wage applied once the player is sold on. If you're going to buy a Nordgen fast trainer, you need to keep him a long time to recoup your outlay, not as a fast buck resell.
