Ideal Rats Room/TAS/MS, can go wrong due to guard behavior
Sometimes the second guard hears the splash early, you need to do an early diagonal!
Old Stage 05 Info
Up to 15 frames faster than knocking out the guard, just make sure not to knock too close, causing him to go around the way you are going. At the same time, don't knock too far away, causing him to spot you as you go down.
More consistent strategy for this guard, that's just as fast as the knock. Just be careful on your positioning.
