How are you measuring that 204F on the Bric?  Thermister on the group 
head? Or is that already built in?
Who woke up the engineer in me?

Thermofilter (& Fluke 51-II, both borrowed from Greg), designed specifically
to measure shot temps. Available @ EPNW. So not actually measuring that
specific shot but have done literally (or seemingly) hundreds of test shots
dialing in my HX Surf & Go technique on the Bricoletta for shot temps
consistently within <1F variance, any shot temp I target between 198-206F.
One series of 24 back to back shots with screen flush and PF wiggle
inbetween each shot, about 40sec from end of wiggle to start of next shot,
only off by more than 1F on one with many within .03F a few dead on and
overall 24 shot average 0.7F variance. During that series I tried six 200F
shots in a row with 0.4F avg variance, then started calling shot temps up
and down the scale. It's a bit tougher to as accurately nail a 199F shot
then follow it with a 205F etc!

I had a revelation some time ago.  The HX "overheating problem" is 
not seen as a problem for those who know what do to with it, is 
it?  It is a way for the Barista to pull whatever temperature shot 
they want without all the fancy gadgetry.  You certainly sound like 
you are on your way.
BTW, can you on or off list link me to that TC you mentioned.

Exactly! I thought I didn't want an HX because of having to surf until doing
enough studying and it sinking in. If someone only pulls shots of one blend
or SO at a time then it isn't as beneficial. But if you're the type that
likes variety daily, sometime pulling back to back shots for different
people of different beans it's really great. Though even if pulling shots of
the same bean gives ability to easily experiment with the effects of small
shot temp changes on the shot which is a benefit. 
Lots of info' on the 'Thermofilter' on HB. I don't own one, Greg bought one
which I've borrowed. (and a Fluke 51-II to use with it)

True. I''l pull one coffee at 201, another at 203. just depends.
There is a theory which states that if ever anyone discovers 
exactly what the Universe is for and why it is here, it will 
instantly disappear and be replaced by something even more 
bizarre and inexplicable.
There is another theory which states that this has already happened.
