Good feedback. I think she is really working on her serve - and the biggest part seems to be "mental" - finishing off matches. I read a report that Stefano came down really hard on her after her loss to Chanda. People could over hear them in the hall, and he told her that she is better and should not have lost. Apparently Jen gives it right back, (just like on court). She said that maybe Chanda was the better player that day, and that she did her best.
I know she likes have Steven there as he is more of a buffer. Much more mellow, and positive. So it makes for a good team.
