One thing that helped me was a mini dry run. I timed how long our usual that model and starting temperature needed on the low setting to reach barely warm while swirling in between then I use that time at night so I am not guessing which, yeah i still check a drop from a couple sides of the nipple on my wrist to make sure there are no hot patches. Pull a little early because carryover heat is real and you can always give it another 20 seconds if it is cooler than you like.
