There you can set the minimum number of hands for what the numbers count as valid. This minimum number of hands threshold has been added to avoid the distortion by players where you have e.g. only 15 hands.
This is also important for the "#Reads" column.
The first digit shows the number of players you have "enough" hands on (regarding to "main"->"options"->"profile"). The second digit shows how many player you have any hands from.
E.g. "4/6" means there are 4 players with at least "100" hands and 6 players with at least "0" hands.
The "#Loser" column just tells you how many players "Total Won" statistic is below zero at this table.
