I always try to maximize training for my team. If I'm training 2-position training, I will buy players so that I have 6 players to train. I will not switch training week by week, at least not from 1-position to 2-position training....(like seasons 29-31). My suggestion is that you train OD first or last but not every third week.
Another thing which might be important is elastic effect. 1vs1 is normally best to train first (at least before PA and OD). Also IS and ID before REB.
Training will slowdown about 10% per year.
My personal preference is a bit higher driving....Otherwise I like goals for your trainees
