I'm not sure I understood your question clearly but I thought there is a 'soil type', shade, 'sprinkler head' types for each zone. You just need to set the same setting for each zone and the watering will come out the same right?

I've added more to the question to try and better explain the issue of two zones covering the exact same piece of grass. Thanks, Ken
