Flex daily recommended time watering too much

that I create, and it waters 2x a week for 161m each time.

Flex daily doesn’t have a set interval so it’s difficult to compare to a fixed schedule. In some months you will water more frequently, in others less frequently. We had a few significant precipitation events in Colorado and at the end of August I didn’t water for close to two weeks. In October I’ll probably only water every 7-10 days based on the weather. The great thing is that they are dynamic. If you do feel like the duration is too much you can always dial it down. Duration is largely derived from root zone depth, nozzle type, and soil type. It looks like you’ve modified available water (derived from the soil type) and the nozzle inches per hour away from the defaults. That is one of the reasons why your durations might be a bit longer.

We try to water more deep and infrequent to promote healthier, drought tolerant roots.

Thank you for the clarification!
I’ve modified the Available Water based on a Web Soil Survey as instructed here: https://drive.google.com/file/d/0BwuNWbi9blyialJzSWxRQnRTcDQ/view

The Nozzle inches per hour was modified based on a physical rain gauge test in each of my zones.

The one thing that I still want to do is determine actual root depth. I will get that in the spring as I just recently overseeded and have a lot of new growth coming in.

All of these questions are coming from trying to understand how the system works to make sure my lawn is getting the best watering application.
Watering deeply and infrequent, as you mentioned, is also a goal of mine, as long as I’m obtaining 1 - 1.5" of water per week.
I guess I was just thrown off by the 7 hour duration. Just seems like a very long time!
