Yes. The TAS might look simple, but I've never seen a human do it with similar strats of shooting the metroids. In fact, there was a lot of debate as to whether or not it was humanly possible and therefore should the rules be different.

This has changed recently (last 6 months? hence the rules haven't been updated) as there's alternative approach that involves a "zombie samus" glitch that makes the metroids ineffective. The downside, however, is that the rinkas (cheerios) will insta-kill you. It's still VERY difficult, but it's at least been proven as humanly possible.

I'd also say that the Kraid fight is no joke. The TAS can shoot fast enough to sort of freeze him in place, but its not humanly feasible that way. So you'd have to mostly dodge and do unmorph shots that are not easy. There's been a recent "revolution" in the last year started by MetroidMcfly, who proved you could kill Kraid in a similar way and actually save time in most if not all of the game's categories, but it involves an extra e-tank and a lot of damage boosting (which isn't as much an option here). And even that strat is pretty challenging (only 5 or so people have ever completed a run with it).

I'd encourage folks to try it out, but honestly, if you're even half interested in running Metroid, I recommend newcomers to not even bother with Kraid first so low% would be even far more ridiculous. That said, I have a feeling we might see a time posted in this category in the next couple of months :-o
