I'd go with number 2 since you posted. If you hadn't posted I'd go with number 3, but then I wouldn't have known about it so that rules out number 3. But then you did take the time to type in rotation backwards, so that puts you into category number 1 . If you hadn't posted and hadn't noticed then I'd pick number 4. If it were me and my bike I'd just do number 2 and not post about it.
