An update:
Yesterday we got 1.1 inches of rain according to the moisture graph so I am now at 110% moisture content. Forecast for today is .3 inches net of evaporation. So the 110% cap means that .3 inches of moisture is in the soil (no standing water) but not accounted for. Average evaporation for the week is about 0.04 inches so it will be a while before things catch up. Rain is forecast again for Friday, so no Manual Fill is needed yet.
