Console:

visual frame 1:
press R in unpause lag
visual frame 2:
crouches

what I'd expect:
hold R for entire first visual frame
2 visual frames of nothing
crouches on 3rd visual frame

nothing ever happens

Thus, if you input R on the third input frame (by this I mean be paused at the start of the third input frame, hold R, then advance 1 input frame; this brings you to the first input frame of the next visual frame) of a given visual frame, then that input will register and count as being pressed on the following visual frame. After that visual frame, there will be two entire visual frames during which nothing happens before link crouches at the start of the next visual frame.
