Hanyu's 4S entrance is not "standard", stop saying that. If you look at Max Aaron or Kevin Reynolds or Brian Joubert, they don't do that much into their 4S. Looking at it closely again, you're right that it's mohawk-3-mohawk, but that's a more difficult entrance than just a 3 turn (which is what Patrick does). Completely disagree still that Chan's other lead-ins are more difficult. Doing ONE difficult turn (a rocker is the easiest of the difficult turns for maintaining speed, btw, it doesn't have counter-rotation) and then giving yourself 5 seconds to setup a jump is not more difficult than doing steps directly into a jump.
