Highest toss when serving

Hello! I commented the PingSkills YouTube video High Toss Serve with a question and was recommended to ask the question also here. My comment was:

Who has the highest toss when serving? Zhimin Jiao had a very high toss: https://www.youtube.com/watch?v=lOpXdk_gYow Is there a world record in this too?

Hi Magnus,

That is a good High Toss serve by Zhimin Jiao...

I don't know who has the record... I think it depends on the height of the roof too.

Anyone have a nomination for the Highest Toss?
