I was duplicating shots in real time...
I pulled the PF out and ran a timer to to put it back in the group as if I was running the grinder, distribute grinds, tamp and lock & load back in the group. It's roughly about 40 seconds between the shots.
The machine is up to temp after 2 shots from a cold start (3rd shot is usually dead on). After that it's stable for at least the next 5 minutes, if it's been idle longer than that - just pull 2 blanks to get it back up.
They're pretty stable machines, I've had readings where the temp locked at 199.4 for almost an entire shot time (the control panel was set at 93C). Ambient temperature, humidity and incoming water are also factors, the machines do a good job of keeping the target in the crosshairs.
When I get some time I'd like to run extensive tests on video with the original Vivaldi S1 for comparison. I remember getting some impressive numbers on that machine as well.

Yes and No, I was trying to be random and this is the series of thermo tests we're looking at on the video clips. Random is more real world but if you wait exactly for the lights to stop blinking after a flush and the PF is loaded and ready, then you'll get even more accuracy out of your Vivaldi.
I was trying to trip up the machine by staggering it a bit here and there, when I said about 40 seconds between the shots, I'd pull some at 30 seconds and some at 50 just to make it more "real world".
