Yes, 68 to 80 are somewhat similar. I obviously meant 68-86.
But 68-80 IS similar, and it's exactly why F is better, because we have the 70-80 band. But that's exactly the point, 68 and 86 are NOT similar temps, hence being in separate 80-90 band.
If you read the discussion that you were actually having to me, we were obviously talking about 20-30c, which is 68-86F. And it was mentioned several times in this thread. And the context of my reply made it abundantly clear I meant 68-86
And 20-30 is more meaningful to me than 68-86. That’s it.
Of course it is, because 68-86 is just the translation. No one would actually use that range. But that's my whole point, 60-70 and 70-80 are better, more meaningful ranges
After all that you're fine with "eh it's just translation." then why not try a system that has some meaning to it at all instead of arbitrary numbers. At least that's what literally everyone else is saying to you in the comment section.
And hey you can decide 20-25 is not T-shirt weather for yourself and 25-30 is. Crazy right?
