Thanks for writing all of that, it's very interesting! I can see how that would be an effective system, but as you said, very difficult to implement in the U.S. anytime soon. Even making some incremental changes would help, as I would think there would be good evidence from systems like yours. We shall see I guess!
While I can concede your point that it’s feasible and possibly even more practical to open from the stem, I gotta say that since switching to the other end years ago(because I saw a similar thread on reddit), it’s been super easy and I’ve had zero issues. The stem just has a higher rate of fucking up, but it’s not like either end will fully decimate the banana. Peeling properly after it’s opened is an easy fix either way.
