I have set my Hud Filter "Filter for # players" to "if # players = 9, then include stats where players between 8 and 10". Also I have the rule "if # players = 4, then include stats where players between 3 and 5".
Now when I play at a Zoom Full ring table where only 4 people are sitting (because the pool has few players), then the HUD shows the stats of hands that where played with 8 to 10 people (and not 3 to 5 people as it should).
