I'm confused about watering time unt.

For example, under basic zone settings, it shows a suggested watering time of 15 minutes 8 seconds. That seems about right based on intuition.

But when I go to Programs and edit a specific stations , it shows a suggested watering time of 45 minutes 24 sec. Exactly three times the recommended daily watering time.

That might make sense if I was watering three times a week. But I'm not, I'm watering every 3rd day, which would make it an average of 2.33 times a week

This is very confusing.

Does the RainMachine take the station water time as a weekly total and divide by the approximate number of times it waters a week to find the recommended daily watering time?
