Hi @mschex, thanks for posting!
I understand your confusion with the numbers. Let's try to break it down a bit. In reporting we do the following math:
- Take the square footage of 1000 feet (defaulted in the Advanced Settings) and multiplying that by the precipitation rate of the nozzle you choose per zone
- Divide #1 by the constant 96.25.
- Multiply #3 by the duration/length that you run your zone.
If you'd like to email our support team [email@example.com] your Rachio username and/or Iro serial number, we'd be happy to review your zone settings in detail and double check the math for you.
Let me know if this helps answer your question.
Thanks! We're excited too
