The MF turn takes up a LARGE amount of space, which means the force of doing the turn is spread out over a much larger area. You experience more force on MF's turn, but that force is spread out more, whereas IJST's turn will not have as much force total, but it will take place in a less amount of time and space. So it all depends on the force/time ratio on how much force you feel at that instant.
