How many Sound Class Mix refs or pushes is too much?

Hello,
Main question: How many Sound Mix refs is too much when using the au.soundmixes.debug command? Or, is it okay to continually push the same sound mixes over and over again? Is tens of thousands of refs to the same sound mix okay?

I used a very popular menu system marketplace addon as the basis for my main menu system. I noticed that their menu audio system pushes a new sound mix every time a sound slider is updated. So, if you are adjusting the music volume slider for example, every time the slider moves, a new sound class mix (of the same sound mix) is pushed, resulting in tens of thousands of refs to that sound mix. This seemed a little excessive.

Since the asset is so popular on the marketplace I assumed this was ok. But I just want to confirm with someone else.
