MK4 is to hard

After the Right beam starts, it's safe to go ahead and move over there before the Left beam starts? You don't have to wait for the animation to complete?

For what it's worth, the vast majority of telegraphed attacks in this game are instant snapshots rather than sustained damage; in those cases, you can move in before the animation is complete, because the damage has already been calculated/resolved when the animation started. (And yes, this is one of those.)

I say "the vast majority" because there are exceptions. But if you get used to dodging into mechanics after they go off but before the animation is done, you will very quickly find the handful of exceptions scattered throughout the game. Trust me on that; I speak from experience here.
