I've got a machine on the bench now that is crazy three group fast, and does four ounces in five seconds. That is disconcerting at first; but now I'm hooked, and it will be hard to go back to 15 second steaming.
Use a 12 ounce jug, that's the right size
Purge the wand very thoroughly, at that speed, if you send in any water, you're toast.
Start with the tip at the bottom and engage the steam. Draw the tip up carefully until you get a roil. if you hear any if the the supposed frothing sounds like tearing or sucking, you're (soggy) toast.
Never hold the jug by the handle, you will have no control. Hold it at the rim and use a finger to test the bottom for temperature. Stop frothing as soon as it gets uncomfortably hot. The milk should be sweet and creamy like eggnog, not particularly foamy, when it is perfect. It will firm up after a few seconds, and at this steaming pace, the shot won't finish until after you've steamed, and cleaned and purged the wand (benefits of speed).
So enjoy, insanely fast steaming can be fun.
