My city water

Just moved to a new house a few months ago and the old softener was useless. I have 16 total grains of hardness, 8 for the water (prior water test and hatch kit) I also have 2 ppm iron, .02 of manganese.
I purchased a 9100sxt twin tank softer. Each tank has 1.5 cruft of SST-60 resin. 48k total capacity per tank. I then added a resup auto feeder to the brine tank. Prior to the softener I added a 20" big blue 1" diameter filter to get rid of sediment (50 micron washable filter).
Everything seems to be working well and I've just started to monitor usage. I want to make sure I have my calculations and settings right. We have 3 full baths, regular tubs and 2 young kids so I went with 60 gpp. To convert iron to hardness I used 4. When searching the internet I saw numbers from 2-5 being used.
Hardness + (iron x 4) ) = 8 + (2 x 4) = 16 hardness
4 people x 60 = 240
240 x 7 = 1680 gal/week
1680 x 16 = 26880 rounded up to 27k
6lbs of salt per 1 cuft of resin and my flow rate is .5 gpm
So for 9 lbs I need 6 min brine fill to get 3 gal of water
So my current settings are
C=27
H=16
BF=6 min
DO = 7 days
SF = 0 (Dual tank so no safety factor
All the rest are default
According to the controller with the above settings I have 1687 gal of water before the tanks switch or 7 days.
I've been reading with iron above 2 ppm you should regenerate more often. Should I make any changes? I finally have time to monitor our usage and I don't know how often we regenerate.
Is there anything else I should consider?
Thanks
