@johnny2678 That moisture graph is not for the original poster. I just happen to have back-to-back watering. I wanted to give him an example of what the graph can tell you. I'm fairly new as well, so I was also looking for a sanity check. You confirmed what I thought, which is that the duration will not change, but the frequency will. As for your EVT question, I'm in the Arizona desert, so it's warm and dry. Here's my weather station is prediction for most of that time period.
Tons of sun, and 8-20% humidity for the lowest humidity points which occur mid-day. It sure seems that would push that EVT pretty high no ?
