I bought a used Gaggia Classic a few months ago and just recently moved to a bottomless portafilter. I'm worried my shots are coming out too fast or I'm stopping the brew too soon. Here are the details of the brew in the photos and video.

\* Gaggia classic preheated for about 30 minutes and purged to avoid burning coffee 

\* 1zpresso J Ultra at 1.00 (finest setting recommended for espresso) 

\* El Gran Cafe Espresso No. 7 from Antigua roasted on August 5th (unsure if dark or medium)

\* Tamped with Normcore v4 at 25lbs 

\* 18 grams with about a 38 gram yield 

\* Took about 20 seconds total 

The puck also seems like it has more water than when I used my portafilter with the double spout. It also seems a bit uneven. It also slushed out of the basket rather than popping out solid.

My main concerns are that my coffee is getting brewed too fast or that I'm stopping it too early. The flavor is decent, but maybe a bit thin. I'm curious if I'm getting the most out of this that I can with my current equipment.

Thank you!
