The % in the control boxes are calculated as follows:
Number of frequencies processing/processed * 100 / Number of frequencies loaded.
Another way of putting this is Step # * 100 / Total Steps in program.
Therefore, in the event of a program with only 1 frequency, it will always show 100%
It is not a gauge of how much time has passed. Although you could somewhat use it in this fashion if all your frequencies use the same exact dwell time.
I also hope you have structured your programs in remote mode in a way that repeats sections over that extended run time. If they are only running once a day, I suspect you will have terrible efficacy rates.
