would I then set the K capacity to what is calculated based on your calculator
Correct. The Capacity setting should be the capacity the salt dose will regenerate, not the total capacity of the resin. A 6 lb salt setting is efficient and will regenerate 20K grains of usable capacity with 1 cuft of resin.
Gary indicated doing 2 - 15lb regen cycles as the entire capacity of your softener had been exhausted.
The DO (days override) setting is normally only utilized to force a regeneration if a regen cycle has not been performed within an extended time period such as when you are away on vacation. You could set the DO to a few days beyond the usual expected regeneration period.
As you state that your Model 100 default salt setting is 9.5 lbs, is your softener settings and capacity different than that indicated in the specifications linked to above, and the User manual here?: http://www.3mwater.com/media/catalog/product/pdfs/3MWTS_Manual.pdf
These PDF documents specify a manufacturer (3M) salt setting of 6 lbs to regenerate 21,600 grains of capacity while the maximum capacity is 29K when regenerating with 16 lbs of salt.
