PS, curiosity got the better of me, and I just checked Crank Bros site. To be precise, it appears the dotted-cleat-left-or-right position impacts RELEASE ANGLE, as distinct from FLOAT which they define as
Float is the amount of unrestricted movement the cleat has within the pedal when the cleat is engaged. Most riders require a small amount of float for healthy knees. Crank Brothers pedals have 6 degrees of rotational float.
I assume the larger-than-I-expected angle of rotation between the lower float number and the higher release angle number is basically restricted movement in the process of disengaging from the pedal. So my comment quoted is apparently wrong, the float is not adjustable.
