Alright, did not expect that. To me, it's just that the food I'm trying to heat often enough varies in terms of amount or how much water is in there, so that it just seems extremely futile to try to heat it precisely. But yeah, I can see dog food or such being consistent enough that this works.
Generally high is too high for most foods, where it overcooks the outsides and still cold in the middle. Regulating the power setting and time is like using the settings on a stove and taking stuff off when done.
Melting cheese, heating mashed potatoes, and a ton of other things are just better with some small tweaks to the time and power. Hitting the +30 seconds is like putting the stove on high and cooking in 30 second increments.
People that thing microwaves suck to heat up food are just rawdogging the +30 seconds button.
So I agree with this, however, microwaves are absolutely one of the worst ways to heat up food, in most situations (but they're super fast, so...)
That said, there is a lot of finesse, particularly when it comes to reheating food, that it seems like so many people never figured out.
Always gotta reheat food on power level 8 (Sometimes I'll blast it for 15-20 sec on high after that just to make sure nothing is lukewarm in the center).
