The same thing must have happened to me. :-) I got a bit confused with all the sprite, pixel and cycle counting and started expecting sprites, where they shouldn't be. The sprite offset is always five pixels. I also have to revise my three sprite theory a bit. As you mentioned, hitting RESPx for all possible copies is a narrow target. That seems to be true for all values of NUSIZx. Only rehits at cycles 6, 11 and 22 get you all sprite copies and only, if they hit a sprite to be displayed. Sprites, that are trailing on the left border are a bit different, though. I think the rule here is to rehit RESPx anytime before the last copy of the set has been started to display. Then you'll get all copies too. But I'm not completely sure about this.
