Hey Joe,
I would start at what ever gives you around 200F as a baseline after a certain duration of flush time and warm sufficient warm up time. You want to make sure that if you are adjusting your pressurestat, that you still have a good amount of steam power if you are steaming milk. Other T1 users could probably recommend a good setting and general flush time. Once you get there, then I would suggest just using taste to decide where to go. If the coffee is tasting too bitter, maybe flush a few more seconds. Too sour, then don't flush as long. If you are updosing with more coffee, it will generally require a slightly higher temp, maybe a degree or so.
With a HX machine like yours and mine, the scace is a good tool for a ballpark temp and figuring out how your machine behaves. I bought it for the ability to dial in espresso machines for wholesale customers once my roastery is up and running. It is a bit more useful for dialing in a PID'd machine, especially where there is an offset between what the PID reads and the actual temperature at the group.
Cheers,
Kaelin
