A New(?) Suggestion for tracking metric

[Nicholasp27]

forgive me if this is already in some of the tracking programs/spreadsheets or if this is already known, but i was wondering about the usefulness of grabbing your chip stack at each level (and # of players left at table) in each tourney and graphing that trend...knowing that you are shortstack when down to 4 players 80% of the time could be useful information...seems like knowing how u trend in varying levels and players left would tell u more about how passive/aggressive you are being on the bubble and with stealing than just itm% or 1/2/3 distribution...
