Guigan12, I just started to pull shots as you describe and am very happy with the results.
Yes, I have been backing off the lever pressure as I'm toward the end of the shot.
It is hot, though maybe not as much difference as you expect.
At 0.5 bar steam temperature is almost 112 Celsius (233F).
At 1.0 bar it is 120 Celsius (249 F).
I installed the heat sink to prevent overheating, but then it took so long for the group head to reach temperature.
Therefore I slowly increased the pressure, until the temperature is stable at 94 C (201 F).
I need a heating flush for the first shot and can pull 5 shots in a row easily.
And that pretty often happens....
Good to hear you like the results of your technique.
I'm still improving mine.
