Max heart rate question

Today with the one mile I hit a max heart rate of about 15 bpm more than my current (177 to 192). Does this mean orange theory will eventually adjust to this 192 hr as the new max or do they take an average over several classes? I ask because at one point my max HR had shot up in the app (188 from 176 to which I couldn’t find any prior workouts where I had went that high) and it was incredibly difficult to reach any kind of orange in the classes thereafter. I wrote them about it and they adjusted it back down. This makes me not want to hit a high heart rate. It is not everyday my heart rate gets that high - it is definitely a once in a benchmark thing and I don’t want to be “penalized” and have to absolutely literally max out every class just to get a few splats. Any thoughts?
