I'm considering purchasing an MCH6. Reading the manual it says that they aren't for continuous use, but I can't find anything that says how that's defined. Am I missing something, or is there some general rule of thumb that I'm ignorant of?

Recreational sports scuba compressors have no defined "use" hence the lack of written definition.
Used in this context it is subject to your opinion and "you" the end users "feelings"
This is why also you only hear and are led to believe the 40% nitrox rule but will never see it in writing from manufacturers or if in the rare occations you do on a new air compressor it is it is always subject to very heavy "user conditions" such as used only in conjunction with a cheap membrane tube.
Also why you will never hear what the test percentage is used above the 40% maximum so called "rule"
Now ask yourself the question if your compressor runs for say 30 minutes filling a cylinder how much "hotter" does it get when filling two, or four of six. The answer is it doesen't but the real reason for this intermittent use condition is because of poor design, weak components and running it peddle to the metal.
This is to enabe the re sellers, dive shops etc to answer the single most asked question by folk considering buying a new compressor. And the single number one question is ............ "How long does it take to fill a tank." with the number two question being how much does it cost.
So what's the "rule" for highest mix that's ok in a compressor, from your perspective?
edit: should better ask what are they tested at, and what do you feel comfortable doing?
and what do you feel comfortable doing?
I often run mine for 2 or 3 hours only stopping it to refuel, filling up to 10 tanks some to 300bar.I'm considering purchasing an MCH6.
