I can't speak to the consolidation part, but I can speak to consistency.
The idea is you're removing tamping as a variable, just as you removed dose as a variable by measuring it. Assuming your machine is consistent the only other variable is the grind setting. There is, of course, distribution. Which can be an issue, some obsess over it IMO. Theres a technique called the WDT (Weiss distribution technique, if I'm remembering right and spelling the name right). The funny thing is if you ever watch one of Phil McKnight's videos on the Breville site you'll see his distribution technique is very simple and quick.
I have a saying, tamp lightly and grind finer. That is, let the grinder do the work for you. 30# is just a number. If you simply lean into it a little you're probably there. Don't sweat the number just try to do it the same pressure. Everyone tamps & doses a little differently. That's why I suggest to coffee shops when I train that they keep a particular Barista on the machine for a while once everything is set for him/her.
You'll find your level, so to speak. In the mean time you're the Roaster's best friend there!

Ok, getting there. This morning had a decent shot at 32g out/18g in. When I had my silvia, I was tamping hard. I'm curious about this "consolidation" theory as it makes sense to value consistency/level over fussing over getting to exactly 30lbs of pressure.
What is the theory behind consolidation? Is there any other online research where I can read about this/get some basic guidelines to this "new" method?

Im glad they opened it up for home descaling. Still not sure about its asian production or excessive use of plastic internals. But it's a big step in the right direction. The steam pressure adjustment is definitely a cool feature as well. That razor thing that they patented is a joke though, and a great example of how companies like this screw up the industry. All I can think of was this: which has been around for years now.

Good deal Voodoo. Sounds like you're getting dialed in.
Acasabia- I'm with you on the descaling, our water is pretty hard and it causes issues on everything that uses hot water. The razor had me wondering about disturbing the puck after tamping. I thought that was a no-no but then I haven't used it so who knows.
This is normal. As the machine gets used the gasket will form to the shape of the PF. As that occurs you will need to push it on tighter. The "locked ," arrow is essentially just there as a minimum tightness to make sure it doesnt fly off during a shot. Tighten it as much as you can, on many machines this is more than 30 degrees past "locked."
