The given presets are only rough estimates for a solid trainer with 10 assistants at 100% intensity...

Remark: The input number of weeks for the reference age is only of theoretical meaning, because the player is getting older during training, i.e. a 17.5 years old player (mid of the season) needs slightly longer than with just 17! Giving any two of the three numbers in the red line will calculate the third!
