I think there is something wrong with the percentages. For example three position training for pressure (sg/sf/pf) and two position training (sg/sf) and one position (sg) is all at 80 percent. Should the three position and two position be training be slower than the one position training? or am just not looking at it the right way?
Training at Sf is at 70 percent for pressure also much slower than two and three position training.
No, there's no problem. Single position training at SF is 70% as fast as single position training at PG. Three position SG/SF/PF is 80% as fast as three position PG/SG/SF. All of the other factors that affect training speed (age, elastic effect, trainer level, minutes, etc) will still apply; the 80/70/60/50 is simply an additional "out of position" modifier.
