That is a very good point Mike, but I believe you could get around watering been scheduled two days in a row by using even restrictions if that allows.
If you live in a hot area like I do and have garden watering restrictions applied to only odd days after 4pm, having two odd days back to back is a bonus!
The only reason I noticed this problem was we had a few weeks of very high temperatures, watering only occurred on the 27th and 1st and the four days in between nothing happened when there should have been two days of watering squeezed in there (29th and 31st).
