I don't know any of the planners mentioned but remember they also have to schedule Line Checks and Theatre Quals not just OE. I was once scheduled to DH to NRT to give a Line Check the next day to SIN. On the bus to the hotel I was talking to another pilot who told me he was a reserve called out to fly to SIN the next day. The original CA called in sick for that leg ( Must of known I was coming). I was rescheduled to DH to HNL to do a Line check the next day to ATL. That flight cancelled so I DH'd back to base. That is what these planners have to deal with on a regular basis. This was on the A330. I can't imagine what it is like on a large fleet
