Wow, you guys are still going at it! Do you guys sleep? I am in California, so your time zone can not be that different from mine.
@Dima, I will try Fingering 2 on my left hand too later after I am done with my work..! I will also try your another suggestion, adlib and 5-2 4-1 4-1 5-2. But my conclusion is that there are many options of fingering, and each pianist should choose what is most comfortable to maximize the intended musical expression. For my hands, 5-2 3-1 3-1 5-2 seems the most natural, but may be not for everyone.
Thanks for doing that Amy - Dima would have said the same things about me anyway. Do you realize you are breaking in your nail joints on fingers 3 and 4 very often? I use fingertips to play which makes one's hand calmer so I will persist and post to see the difference - watch this space.
Yes, I do know I am breaking in my nail joints

Not just that, I do know my long list of technical problems. I blame on my odd shaped hands as well as my childhood teacher who actually didn't know how to play piano! Only last one year, I am taking a lesson from a real piano teacher, but most teachers are horrified to teach me as I play tons of advanced stuff with horrible techniques with no pain syndrome

Let me know if you notice anything else!
