What is your method of HX brew temperature management?

Managing the brew temperature of heat exchanger espresso machine requires the barista to flush overheated water before beginning an extraction. Several popular methods of determining the proper method flush amount have emerged, as denoted in the poll responses. Some methods rely on "on the fly" usage (e.g., water dance, E61 thermocouple adapter), other methods rely on measurement tools like the thermofilter to determine in advance the best flush regime. What is your method of HX brew temperature management?

Ever since I got my Anita, I've been using the water dance for my temp management. I've been meaning to get a E-61 adapter but keep spending my money elsewhere.

I've gotten pretty comfortable with a few coffees that I get very often such as Redline, Kid O's and Toscano. but when I try a new coffee, it throws me for a loop and I'll end up with a few more bitter or sour shots.

I chose the E61 thermocouple adapter option, but maybe an addendum is in order. I don't have the thermocouple adapter but Eric's adapter using a modified digital thermometer that is mounted in the same location. Using it, I just flush until I reach the temperature I have figured out before hand (mostly trial-and-error, but had use of a thermofilter for a few hours one time) and then pull the shot or rebound and pull.

I've tried to use the water dance as a gauge, but I have a hard time identifying the end of it precisely because the vibe pump is so loud and it's hard to see exactly when it ends. I just hope my thermometer never stops working!

PID and setpoint adjustment so machine stabilizes at nearly perfect brew temperature.

Other: More of the same. On my rotary machine there is a clear auditory drop off at the end of the water dance which demarcates my "start point". So my answer would be Listen. From this start point I count in my head "one-thousand, two-thousand, three-thousand" etc. to my desired temperature. This temperature corresponding to the number of counted "thousands" was initially verified and charted (and occasionally re-verified from time to time since then) with my Scace thermofilter. Interesting how with simple counting post-water dance on the A3 I am able to easily and very consistently pull shots at what ever temperature I desire (I'm talking to like within 0.2-0.3 degrees F per reading on this digital thermometer). All made simple with Greg's thermofilter tool and my Fluke!

I flush by time post water dance and use my taste to judge the temperature. When it tastes right I have the correct temperature.

I bought a La Spaziale Vivaldi II. Managing the brew temperature is a breeze now.
