I could be wrong so maybe worth a shout to run it past mistking, If you do figure it out Id love to know how as I would probably end up getting this model,I have seen other posts about this saying you could adapt its usage i.e setting it to come on when your rh drops below 40, then you would still get your humidity spikes throughout the day.
The seconds timer is the way to go as you can set 10 different programmes to mist for different durations at different times
e.g
P0: Mist 25 sec at 8:00 am every day of the week
P1: Mist 2 min at 4:00 pm every day of the week
P2: Mist 4 min at 7:00 pm every Wednesday only
where as the repeat cycle is more like day cycle night cycle with no extra programmable timings e.g
Mist 5 sec every 2 minutes during the day & mist 10 sec every 20 min at night.
