i would say you would more training with more.
Yeah, that's exactly what I used to think and it is easy to assume this. But I asked about this quite recently and Juice commented saying that he thinks 1 position gets exactly double the 2 position training does. This leads me then to assume that 1 position training is more effective IF you can manage the minutes correctly.
That's a big IF because it is a lot harder to get 48 mins each on 1 position training. And each minute missed is worth twice that of 2 position training.
I still 2 postion at the moment, but maybe not next season.
