RS: SF (Percentage Safety Factor)
SF: 15 percent
I would use one of the following 3 pairs:
RS = cr ; cr = base reserve on recent experience
CR = 0 ; 0 is default (leave it or maybe it does not show)
RS = rc ; rc says use gallons vs percent
RC = 300 ; Reserve capacity gallons
RS = SF;
SF = 13 ; percent. (15% would be equiv to 353 gallon reserve with H=17.)
I don't like the RS=SF method, because if I change the hardness or capacity setting, I would need to change the SF number too. RS=rc is much more understandable.
For
DO = 14 ; Day Override (typ 28 if no iron/Mn)
that if fine if you are on city water or have very low iron into the softener
47 or 45 would be OK with a #3 Injector - Yellow. I would have preferred a #2 Injector - Blue, and with that I would use BD=62 or 60 at your salting level. You might want to peek at the injector color, but most people would not do that. On the other hand, most people would have used 60 as the BD number not knowing the injector.
From your BF time, we can infer that you have a 0.25 BLFC.
