perpetual s16 is easier btw

Why is this a 15... The 7-note runs are S+ level..

To get the 'Drill Level 1' title, you have to be better at things other than drilling.

If the drills had just come out consistently, it would have been better, but besides simple drills, there are patterns scattered throughout that consistently drain stamina and confuse the player, such as gallops, jacks, and runs. It's not a song a local 15 player can easily withstand, but since it's relatively clean among upper-mid 15s, it might be easy to clear once you've mastered some of the higher-level songs.
