Keeping Records...

[psari]

What's up guys?

I've recently started playing Heads-Up SNG's on Pokerstars. I like to keep records, but I am unsure of the pertinent information to record? I have been recording:

a) The Date
b) The Opponent
c) My Record against the opponent
d) My overall Record
e) My total profit
f) The time length of the game

What kind of stats should I add? What should I remove from the list? Thanks for the help guys
