For what it's worth, I have a different approach: I take out the basket retention clip and dose/distribute/tamp the basket out of the portafilter. For the 3rd+ shot, I dunk the portafilter in cold water and then lock it in prior to starting. By the time I'm done futzing with the basket, the portafilter is hot again and the group is at temperature.
Dan,
Are you doing this with a bottomless portafilter or a stock one? I've found a stock portafilter has enough thermal mass to do the job on a Millennium Pavoni, but I think Chris (yakster) is finding a bottomless lacks sufficient mass. For the dual-switch pre-Millennium Pavoni (without a PSTAT) I don't even know if a stock portafilter is enough to cool things down that way so that other methods must be used.
