> 20 minutes every 2 hours starts becoming a bit much

I didn't say that it was "20 minutes every 2 hours" - in fact the sentence "If you stop every 2 hours, you don't need the full 20 minutes " says that it's less than that.

Your specific case described "10 mins stop every 6-7 hours" is extreme and of questionable safety. How much fluid did you consume during that time?

I'm not going to say "don't do it", but lets not pretend that it's the average use, or even your average use. So you should not optimise for that at the expense of making other cases worse.

You're also saying that the comparable charging time, even for extreme cases like this, is not all that far off.
