Can someone who has access to a precision robot and controlled environment please check; if one applies the same force on the coin in flipping, with it landing on a (soft) surface at the same height it - will it land the same side every time.

Your comment sniped me into thinking of some over-engineered systems to measure this with the human factor included. Some sort of RFID coin balanced on all axis with an IMU chip that measures the force applied to the force (through acceleration) and the mode and number of rotations of the coin. Maybe a computer vision solution would also work

I guess in theory you could "catch" with the correct call by varying the height of the catching platfrom.

You could read the Diaconis paper?
It is paywalled so I can not.

However, I was unaware that they already conducted said experiment. I am now left confused as to why they would not mention such in the abstract, and refer only to natural experiments and second order measurements.

I shall aquire the paper and learn why.
