The Orbit catch cups have a 16.25 square inch opening. That means 1 inch of water will be 16.25 cubic inches. That’s 266 mL. So:
125 mL / 266 mL = .47 inches
Since you collected that in 10 minutes, you should multiply by 6 to get an hourly rate:
.47 * 6 = 2.82 inches per hour
That zone is putting down a lot of water!
