The only reason my video lags at the end of Sigma 1 is because of my poor choice of weapon. Remember, I used to super X-buster there because I needed to clear out more than one enemy without worrying about timing. However, using rolling shield or well timed torpedos probably would have eliminated the lag. Heck, if I just used regular shots and ignored the Mettools, I would have had just as little lag as you. If you really needed to avoid the shot, rolling shield might work because it sucks up shots. But I'll state this outright... I have no problem with the invulnerability. I'd use it more if it'd save time. Also, at the time, I was recommended, but not forced, to take my Sting sections from 4 to 1, since at least half did not require it to be done. I was just stating that it isn't necessary there. And yes, I agree that dashing looks better, even if a little superfluous. Still, I wonder if you could earn a star with this video...? --Woody EDIT: I'm not so concerned about the X falling thing. Personally, I hate that part of the optimization because you need to retime some sections almost entirely to make sure you aren't sacrificing ground speed for drop speed. Thankfully, there aren't that many large falls in this game that you really need to look out for. asteron: DeHackEd is right in that in some parts, it is not possible to fall at optimal height. Sigma 3 comes to mind.
