@gotMoxie, are your seasonal adjustments reducing or adding time? If there's no adjustment needed, water budgeting will not change the seasonal adjustment.
ET calculations are based on numerous inputs; temperature, hours of sunlight, humidity, wind, etc. Besides days getting longer again, perhaps wind speeds have been higher than average? We could try using a different weather station to see if the data provided is better to what you're experiencing.
@sbillard, I'm curious if you and @gotMoxie are using the same weather station?
It's hard to comment without reviewing the details of the weather data provided. I'll have our support team pull your data logs to review the data we received from your preferred weather station. Usually such discrepancies are weather station related.
Out of curiosity, what would make understanding ET variances and their impacts to watering durations easier for you as a user? Do you think knowing daily ET would help? Seeing changes visually to the weather data? i.e. ET over Temp and other inputs? Let us know how we can make this feature better
