My fork of Morse Walker shows for each virtual QSO, how many stations were trying to connect, and the average number of stations that try to connect over your session.
I've always kind of felt like the simulation steps when adding stations are too discrete. Set to 2, it often hits 0 and you have to call CQ to invite a new caller; set to 3 you might go 20 minutes without draining the pool. I've been thinking about what other controls I could add that would give a more realistic simulation where sometimes it's a deep pileup but it drains more often. None of the ideas I've had yet has satisfied me. But I'm still pondering. Simple controls that also lead to a believable scenario is a tough nut to crack...
