The card analysis showing is your personal analysis of the Boards you have played rather than the overall deal analysis shown on the "Hand" Tab. So if there are 30 boards and you only played 24, the analysis will just be of the 24 played, and if the movement is an Arrow Switch or Howell of the seat that you sat in.

The analysis shows:

HCP - Average High Card Points
Balanced - Total of all Balanced hands including 4333, 4432 or 5332.
Void, Singletons, 2... The total of each suit holding, if you played 24 boards, this should all add up to 96.
