Ι guess my english are bad.
A FT gains 4-5 skills per 15-18% condition loss, but this happens only if his training skills are below 100%.
For example this player is a Fast Trainer.
IF we train this player with Press the Play he certainly not going to gain 4-5 per 15-18% condition loss.
But if we train him with Skill Drill then he will gain 4-5 skill per 15-18% condition loss.
