Soil type... what to choose based on


Hello! Long time lurker, first time poster. Installing my Rachio 3 this weekend and I’d like to dial in my system and give flex daily a try right off the start. I read a nice article on here directing me to where I searched my property. I found that my available water is 0.15 inch/inch which I plan to enter into the Rachio. The site also says that my soil search from 0-40” is 100% Armster Silt Loam. But then it somewhat contradicts itself saying:

0-6” silt loam
6-11” clay loam
11-31” clay
31-79” clay loam

Soooooo… what should I enter into the Rachio?? Any guidance is appreciated.
