So if im correct 24 minutes of 1 position training (for example C training) is as effective for a player as 48 minutes of 2 position training (PF/C),right?
Most likely not. As the training effect is not linear (24 minutes of 1 position training would result in less than 50% of the possible 1 position training effect), the equivalent of one position training to 48 minutes of two position training would be estimated to be in the 30's (rough estimation). However, no one has calculated this as of yet.
