From Training Speed Analysis:
Pressure
PG:
Trains OD @ 2 weeks
~2 weeks --> 1/2 = 0.5 od/week
~ 2.5 weeks --> 1/2.5 = 0.4 od/week
PG/SG:
Trains OD @ 3-4 weeks
~3.5 weeks --> 1/3.5 = 0.286 od/week
~ 4 weeks --> 1/4 = 0.25 od/week
So player A gets 48+ on 2-position training and player B gets 46 minutes on 1-position training.
Player A trains for 0.25-0.286 od
Player B trains for 0.4*0.9-0.5*0.9 = 0.36-0.45 od (Assuming that 46 minutes is equal to 90% training)
Player B trains for 0.4*0.8-0.5*0.8 = 0.32-0.4 od (Assuming that 46 minutes is equal to 80% training)
So I can assume that training is clearly faster in 1-position training.
