Hi Ray, I believe that it would be very beneficial to allow customisation of the algorithm since to me, when I set a program to run every 5 days (for example), I am more interested in the weather in that interval period rather than just the last day. To me it would be ideal if the weather just automatically used averages over the interval period as this seems more intuitive to me. I’m no great programmer so I think it might be a little beyond me to do my own customisation.
