The basket plug will be available to buy from mid-oct apparently.

It's been available from other retailers for a while now.

Cool that plug looks a little easier to use than the breville one, which I have to use kitchen tweezers to get it out. Thanks for the heads up

Guys, could you give me some tips on pressure profiles? Should I maintain a constant pressure, or is it okay to let it decrease? When I set it to 6 bars, it sometimes drops down to 2.

Depends on the coffee, but many seem to benefit from the classic lever profile, which declines over the course of the pull. The Robot appears to do this naturally on its own, unless one bears down and in heavily past the arms' horizontal point (not to good effect, in my experience). If you've done a little experimentation with pressure variance, what does your palate tell you?

This is the second time in as many days that I've seen someone mention that a manual levers does something naturally. It really doesn't. Your lever is not exerting any real pressure to push water through the puck. How can it exert a declining pressure profile naturally? Without resistance, the arms slam down from gravity. I'm genuinely asking because I may be missing something.

The pressure decline or maintenance is 100% based on you. Is it not?

I think there is an unspoken assumption that a steady flow rate is being maintained. In that case pressure usually has to decline over time. Not always though.

I don't agree, since the arms move in an arc, the pressure will not be consistent unless you push harder at the last bit.
You're closer to pushing horizontally at the end than vertically.

I used both a robot and a Flair 58. You have to increase your own pressure on the lever as the shot runs longer to maintain a pressure since resistance diminishes. The Robot isn't unique in this sense, in my experience, but some are reporting that it is enough so that it separates it from other levers.

It's a declining lever profile based on classic spring levers not manual ones. As others have mentioned it's just easy to achieve on the CR, it's not unique to it.
