No, not really - it all depends on how large your batch is and how thick it gets.
Every single piece of new equipment needs to be at least roughly calibrated/dialed-in as a part of establishing a procedure for it, so you need to try it out making a few batches, and keep careful records. Once you’ve made a few batches, you should be comfortable with which settings need to be used when. This is done to one extent or another at pretty much every manufacturing facility everywhere - it’s not just you that has to do this. It’s not that hard, just start from zero and work your way up until the batch is moving around enough.
Keep in mind that the folks making these mixers aren’t making precision equipment either, and so they don’t take particular care to make sure they’re all exactly alike. As a result, a dial setting on a new one I use could produce RPM’s significantly different from what I’ve used in the past, and both could be different from the one you have, so you have to check each mixer you buy. Large companies can afford mixers with tachometers and other instrumentation built in to their mixers that make this process easier, but most of us have to do this the old-fashioned way.
You should be able to see foam visually if you’re beating air into the batch. If your finished batch has too many bubbles/too much foam, then you have a problem with your procedure somewhere. If it doesn’t, then you have nothing to worry about.
