Yes, I agree it's a little cumbersome. We were probably emphasizing flexibility a bit too much when we designed this.

Also, based on some prelim experience with this we advise you don't permanently train as it's possible to "over-train" the filter. i.e. you should do a bit of training (say 30 min) then don't train any more. See how the filter's working.

You may go back in and tune it up a bit (training some more) later but you shouldn't stay in training mode permanently as there isn't much benefit to training beyond a certain point
