Just HOW do you KNOW this information?
As a diversion, go to the park with a friend and some tennis balls.
Get on the rotary spinning wheel thingy (merry-go-round?), sitting directly opposite each other.
Spin the wheel at a good pace, and gently toss the balls between one another.
Really, I don't know it. That is why sometimes I drop or miss the ball. Also, the first place I put my hand when the ball is thrown is likely not the final placement when the ball is caught. The position is adjusted, a posterior, based on what I am seeing. To claim the bees are making building decisions in terms of the displacement used, a posterior, would be to imply they are actually doing calculus. Clearly, that is not the case. That is the difference.
