definitely disable it for now. i only enabled Calibrator when i was over 150 levels in other interval exercises.

Judging relative distance is a great skill. If you can clear rounds of Calibrator even without knowing the exact interval, I'd say carry on. As you know, you're covering specific interval recognition in other games. These skill sets will complement each other over time and eventually merge.

Though for the record, I did what Dima G suggests and disabled Calibrator. But that's because I was failing and not learning. If you are able to judge distances well, you may still benefit from playing.

One thing about Callibrator for me (and I try getting the intervals correct, too). It takes more time than the other exercises. This helps build a little discipline for me to focus for the whole game. But good on you that you can tell which is largest without knowing the particular interval -- good ear!

i didn't know it was possible to estimate relative distance without identifying the exact interval, especially for intervals that are close to each other. it's certainly possible to do when one of the notes is fixed and the other is changing. but is way harder to do when two sets of notes are completely different.
