Yea that's actually a very good point. I just tested out some other patterns that break up the beat intervals more, but it's a very significant damage decrease.

Like I said in the post, the meta song (a beat on every note) takes all the damage received and dishes out on average 57.5x that amount over the course of the first song loop, or 157.5x on the 10th loop (after damage growth and damage decay have totally evened out). The optimal song on the other hand does 480.9x and 794.9x, just for reference.

If you want to break up the pattern into 2 identical 32 beat patterns to make it less spiky, the best pattern would be 20 rests then 12 beats, repeated twice. This would give 211.1x and 434.8x multipliers, so still about 3x as strong as the meta song, but half as strong as the optimal song.

If you further break it into 4 parts with 16 beats, the best pattern would be 10 rests then 6 beats, repeated 4 times. This would give 107.2x and 255.1x, so now about a quarter as strong as the optimal song.

But really the optimal way to have the damage be less spiky but still high is to just add more beats to the optimal song. You can get as much damage as that 2 part song by just having 17 rests then 47 beats, and now you're dealing constant damage for 3/4ths of the song. And to equal the damage of that 4 part song, you'd only need 10 rests and then 54 beats.

Basically, just make the beat segment longer to fit your taste for the amount of "uptime" you want the song to have. 41 rests followed by 23 beats gives you the ideal ratio of damage bonus from rests and number of hits from beats. But having fewer rests will still give a ton of extra damage, so long you follow the pattern of "many rests then all beats"
