Rainfall Calibration

I have had my Sky running for about a week and suspect that the rainfall measurements are overstated. As I purchased the WeatherFlow system primarily for highly local rainfall data as input for my sprinker system controller, it’s important to be able to trust the measurements.

I decided to open a new topic on this to directly ask WeatherFlow staff to comment (to the extent they can without revealing any IP secrets) on how the calibration process works. If possible could you:

a. describe the general self-calibration process
b. comment on what other sources of rainfall data are used to compare against the Sky data
c. predict what length of time (or number of measurable rain events) are required to achieve a reasonable calibration

Thanks. My intent here is to have an idea of how to proceed to use the data in a reliable way.
