We admittedly splurged on the grinder and got another breville product, the Dose Control Pro I think, which was as much as the darn espresso machine. It has a timer and a good grind setting dial, and you can put the portafilter right into it, but I still just grind into a little tupperware container and then measure out by weight with a spoon though, as right into the basket always makes a mess imo.

I've never got the preinfusion step to work the way I want. I tried it a bunch after buying the non-pressurized basket, and found I'd get pours coming out way too fast (like <5s) no matter how hard I tamped, even at >18g in the basket, doing almost exactly what you mentioned! I think they worked okay in the pressurized one though.

I've since settled on ~16.5-17.5g at ~12.5 on the grinder (from 1-50), and tamped briefly about as hard as I can comfortably press. Comes out good enough every time that I stopped timing anything and just pull to the 34g weight (+5-6g of drip after) these days.

I'm inspired to go grab a coffee. :)

Thank you for this great info. I forgot too mention I'm using an older portafilter from a machine I had years ago. I put it in storage when my son was born (counter space) and the pump siezed while in storage. I was unable up repair it and my wife took pity on me getting me the current one for me as a gift. :) I kept the old portafilter as it much heavier than the one that came with the machine and seems to pull a better shot.
