In my opinion a 14g:15ml, one-pull on the PonteVecchio is simply too high a brew ratio. It can taste good, but it is really very concentrated. One pull on the PV only yields 15 mls, and even with an added Fellini pre-infusion you're in a very high brew ratio range. A "normal" ristretto is 14g:30ml.
Hal - it would be like dosing 14g on your commercial lever, and stopping the pull when there is about 15 ml in the cup.
So, for the past 3-4 years I've been taking 2 or more pulls with the PV double basket. I don't see any fundemental difference between one pull vs. two pulls, as long as the puck is not disturbed. Hal - try stopping the lever on you commerical machine for about 5 secs halfway through the pull, then letting it start again. This is basically the same as a two-pull PV (again, if the puck is not disturbed).
SO, you must grind, dose, and tamp so that the puck is not disturbed. In my opinion a fuller dose and at least a lightly-firm tamp (10 lbs?) is the best way to achieve this. Then grind accordingly. When done properly, for the preinfusion I pull the lever all the way down, then slowly let it rise until a drop falls into the cup. This could take 10 sec, maybe more, and a considerable degree of lever travel. Then I begin the two-pull shot.
And forget the clock entirely. Timing shots is espresso 101, and you graduated from that class before your even ordered the Lusso. I casually noted that my afterlunch espresso on the Caravel yesterday took over 1 minute from the time I started preinfusion until the shot finished pouring.
Trust me, I have not been drinking bitter espresso the past four years.
