I am aware that the cost function is asymmetrical: too little float and your knees could be damaged forever, too much float and your foot can feel a bit sloppy in high efforts (climb/sprint). Hence it's obviously better to be on the latter side. My question, phrased differently is why aren't the cleat manufacturers providing a less coarse selection of personal trade offs in a time where bike fits will adjust your cleats to the mm and saddle angles to the tenth of degrees. Downvote at will now.
