I'm hoping that stirred hot wort isn't bad. I used my sanitized paint stir thing and drill. Went from 218 to 90 in 4 minutes with a homemade 3/8" 25' immersion chiller. Another 30 seconds I was at 80. Arm got tired, needed a beer. So I typed this post.

80 to 70 a little slower. Guessing that's cuz I'm getting closer to ground water temp (50).

Yeah, the smaller the delta, the slower the cooling.

Delta dawn must have been here cuz I've never chilled this fast.

That is a good idea, I'm too curious if for some unknown reason this isn't recommended....

You don't want to aerate hot wort, so as long as it wasn't that fast no problem. Though 4 minute cooling is awesome. Keeping the wort moving over the IC is good and there have been a few innovative ideas over the years.

Yep.  That's the main reason I got a pump.
