Thanks Doram and MediiumRoastSteam (MRS)
I am going to try MRS’s portafilter handle rotation/pressure trick to try and stop the puck from sticking. If I don’t see a puck fracture, then that issue is solved. Stay tuned.
As for IMS 15 Precision Screen basket, if I updose, I presume that if I keep the same brew ratio with this particular bean, the following will happen:
1. The shot will run longer, due to the increased puck thickness.
2. If I choose to maintain the same shot time (especially if it runs really long, without flow profiling, which the Lelit Elizabeth cannot do), then I will have to grind coarser.
3. The speed and vertical evenness of water penetration into the puck might be somewhat reduced (an espresso pundit stated on their site that thinner but still high flow baskets improve the evenness of vertical water penetration into the puck, which they said was a good thing). Thoughts on this?
4. The amount of headspace between the top of the puck and the screen will be reduced. Time for a nickel test!
All of the above may be ok. Still, given the above 4 effects of increasing the dose, while maintaining the same brew ratio and possibly time), you may have other benefits/rationale in mind for increasing the dose for this basket. Can you elaborate on these. Is it simply that the basket is designed for a larger dose and would not tolerate more than 1g variance above or below its rated capacity?
