This route is at least 4.03 seconds (242 frames) faster than the one used in the currently published run. I do not plan on improving that TAS; this is merely a demonstration proving that taking the bonus round path is indeed faster than the standard route. This is also not super optimized for finer movements or reducing lag, so the time save could be even greater.
HP was set to 2 from the cheats menu for ease of setup. You must have 1 HP by the bonus round to lose it as fast as possible. In a full-game TAS setting, I would expect the player to have 1 HP leaving Day 7: Rock N Roller, so gaining an HP from a health drop between then and this level should be no problem.
