These have all been passed, without any mods (this means you, speed mods and So Deep), except as noted (i.e. for bag).





600 beats per minute is dumb. On Max. (standard), I can get a 100 combo, keeping my health bar full for most of the song. Then it gets to 600 beats per minute, and I miss almost every note. By going into the section healthy and flailing blindly, I've made it as far as planting the last hold before dying, but can't quite beat it.

Now, so far this is just a whiny rant. It's about to get scientific. There are, obviously, two opposed factors here: how long you have to respond to a note, and how long it takes you to respond to a note. We'll deal with them in order.

My experiments show that it takes about 1.8 seconds for a note to get from the bottom of the screen to the top at 150 beats per minute. It follows that it takes about half a second for a note to get from the bottom to the top at 600 bpm. So you have half a second to respond.

That response is moving a leg to the correct panel. We'll assume that you have to move your foot about a foot, and can move it at an average speed of 15 mph. It takes about 0.05 seconds. Sounds fine, right? You have nine tenths of the time available to you dedicated to processing. Not so.

First, there's the time it takes to get the impulse from brain to leg. I can't get Google to decide on the order of magnitude of this (speeds quoted range from 4 m/s to 60 m/s); we'll say it goes at 10 m/s and thus takes a full 0.2 seconds. Half of your time is gone.

Now it's just a question of reaction time. It's easy enough to find online tests of this (or just play the gunslinger game in Kirby's Adventure). Mine's around 0.25 seconds when I'm on top of my game. So under ideal conditions, it takes me a half second from photon hitting eye to leg being where it should be.

So, under ideal conditions, reading from the very bottom of the screen, playing at 600 bpm is theoretically possible. Barely.

Why do I need Konami original songs? Not for this kind of crap.

You could always C300 it, y'know. (We won't think any less of you for it, really.) Or run it at a lower speed to memorize. -- AndrewFarmer
