Recalculate is meant for, not just different, actually smaller block size, the vector clip contains 3 things of each vector, vx, vy and thsad, recalculate reads the thsad from one vector, and if it's too high, then the block is kind of "high energy" (complicated) or whatever and the motion estimation is bad and recalculate will divide the large block into 4 smaller blocks and try to match again, so you'll always have the most precise match
