Hi guys, I'm new here and I've really been enjoying this forum so far.
I came across this CFR replication experiment protocol which could provide a COP of 1.2 (The enhanced version can theoretically show a COP of 2). It looks quite easy (possibly a bit dangerous) to replicate although I haven't tried yet myself. I believe there is a video on youtube of a guy replicating it.
What is your take on this ?
