D = 18 years old semi fast trainer will catch up all 3 of them in the long run (meaning even if you dont power train him he will catch up in 3 seaons)
C = meh dont know i wouldnt do it
a = not worth pt
b = not worth pt
none of them are ultra fast trainers tho
The market value of the 20y (A) old is higher than the 18y old, A is a fast trainer and D a slow trainer.
If you have a 18y old with quality 24 and a market value 2,35m or something like that that will be a fast trainer.
