Recently installed a Fleck 5600SXT 64,000 gr capacity, 2.0 cu/ft resin (standard). Brine Line Flow (BLFC): 0.5
4 people in the house averaging 160 gal/day total for the household. Hardness: 20gpg. Water Source: City (no iron)

Looking for programming guidance.

System info (not programmed)
salt lb/cuft = 7.5 ; A choice ( efficiency vs capacity)
BLFC = 0.5 ; Brine Refill rate GPM
cubic ft resin = 2 ; ft3 resin = (nominal grains)/32,000
Compensated hardness = 20 ; including any compensation
People = 4 ; gallons affects reserve calc
Estimated gal/day = 240 ; 60 gal per person typical calc
Estimated days/regen = 8.73 ; Computed days including reserve

Fleck 5600SXT Settings:
DF = Gal ; Units
VT = dF1b ; Downflw/, Single Backwash, black cam
CT = Fd ; Meter Delayed regen trigger
NT = 1 ; Number of tanks
C = 46 ; capacity in 1000 grains
H = 22 ; Hardness-- compensate if needed
RS = rc ; rc says use gallons vs percent
RC = 240 ; Reserve capacity gallons
DO = 30 ; Day Override
RT = 2:00 ; Regen time (default 2 AM)
BW = 5 ; Backwash (minutes)
Bd = 60 ; Brine draw minutes
RR = 5 ; Rapid Rinse minutes
BF = 10 ; Brine fill minutes
FM = ____0.7 ; https://terrylove.com/forums/index.php?attachments/img_fleck5600sxt_flow-png.31592/

Revised based on number from https://terrylove.com/forums/index.php?threads/help-for-programming-fleck-5810.82673/#post-595983
The less salt per cubic ft, the more salt efficient, but more hardness breakthrough.
BLFC 0.5
cubic ft resin 2

Alternative capacity (C) and brine fill (BF) pairs. Round C down.
lb/cuft C= BF=
3.0 27.7 4
3.8 32.2 5
4.5 36.0 6
5.3 39.2 7
6.0 42.0 8
6.8 44.5 9
7.5 46.6 10 #used above
8.3 48.6 11
9.0 50.3 12
9.8 51.9 13
