> Click and click is slower than click+drag, it’s just obviously two extra movements (a full extra press and an extra release).

I don't think this is right, because the second release is irrelevant (a click-click move happens on the second mousedown, not the second mouseup) and the first release can be done in parallel with the mouse movement. So really it is:

mousedown -> drag -> mouseup

vs.

mousedown -> (mouseup while moving) -> mousedown

[reassess_blind]

mouseup has to occur before moving, or it initiates a drag

Not on Lichess. (I'm not sure about other platforms.)

With the click-to-move setting, the piece is activated on mousedown, and dragging is ignored.

Oh I see, I forgot there was a setting. I thought it was always either behaviour, depending on what you do.
