This sounds like a comment from a sleep clinic. "Better yet" means that second phrase is even more important than the first.
Student or Learner
We can now tell whether he is dreaming or not; better yet, we can identify, within one second the instant he begins to dream.
Could you please explain the meaning of better yet?
Looking forward to hearing from you.
Thank you in advance.
It seems "Thank" and "like" don't work.So I express my thanks this way.
