@garmanmd, good morning. Emil here, filling in for @franz. You’re understanding the MAD adjustment correctly in your last post. Lowering the percentage (under 50%) will result in more frequent waterings; whereas increasing the percentage (over 50%) will result in less frequent waterings.
The best way to think about this is like a gas tank. As you know, at 50% your gas tank is half full; but using MAD principals, at 25% it’s 3/4 full and at 75% it’s 1/4 full.
Using MAD, you set the percentage that you want your lawn’s “gas tank” to be refilled at. Everyday we look at how much “fuel” your lawn has used and calculate when/if we’ve hit the refill point (allowed depletion). By default, we set the refill point (allowed depletion) to 50%, however this can be changed to anything from 0-100%; thus the name Management Allowed Depletion, or MAD.
The Moisture Level graphs in the web app will display the percentage of the moisture available within MAD; or how much fuel do you have left before you hit the refill point. As such, if MAD is set to 50% and your Moisture Level graph reads 50%, then your lawn’s “gas tank” is 3/4 full and will be refilled when it’s 1/2 full. Think of it as a percentage of a percentage
I hope this helps explain any confusion in the percentages you saw and provides some framework into how to use MAD as adjustment to match your lawn’s needs. If I’m understanding correctly, reducing MAD to 25% is resulting in the watering schedule you expected?
Let us know if there’s anything else we can help you with.
