EDIT : I later realized you were just sharing and not asking for analysis .. but anyways I will leave it out there ... I had fun watching and thinking ...
Jeff , I saw it right after FZD beat Xu Xin , and I was not even conscious about that when I was thinking that should Jeff change to Shake hand

... but I realized later ... anyways ... what I could see ...
The quality of your game and consistency went up noticably as the match went on and you are playing pretty well ...
1. One thing I noticed and I have that problem too , sometimes you are overshooting the ball because of the larger steps you take .... I think it has something to do with you and me having left knee issues and trying to compensate on the lack of our footwork by taking larger steps ... not sure how bad your knees are but thought I would say be conscious of it and may be you can figure out a way to not fall into that trap ... may be NL can help with some practical tips ...
2. You were missing the loop on spinny wide long push to your forehand , may be you ought to practice it more , may be you are late with the footwork or the timing of the forearm snap is off ..
3. Sometimes if the ball is short topspin and high you are not trying to flip it with your backhand , any reason. the backhand flip does not have to be a banana all the time .. it could be a straight topspin flip , I have found that pretty useful , thought I will ask you why you don't do it ...
In general may be try to serve heavier and shorter and try to setup your loops ... because thats the game most probably you will end up with as you keep improving ... going by the trend all around .. but yes I would strongly say , if you are on vacation and have time and good practice partners , practice serves and your footwork . You can do shadow training off the table as well ... I am sure it will help you a lot when you come back to the game ... Good luck and thanks for sharing .... hope what I said helps ... don't treat it as coaching advise but just take it with a pinch of salt as my personal opinion and do what makes sense to you ...
