as sonny said, you need to regenerate all your basic strategy variations (including insurance) based on what resolution you choose.
i think you are still confused between resolution and estimation though. they are mutually exclusive cooncepts, in that you
dont choose one or the other like your post seems to suggest, you choose one of each. you choose a resolution AND an estimation level. estimation is really just you looking at a stack of say exactly 70 cards and saying that this stack either contains 1 deck or 1.5 decks. if you say the stack contains 1d, you are rounding/estimating to the nearest deck. if you say 1.5 decks, you are estimating/rounding to the nearest half deck. it is seperate from your choice of resolution.
one thing to note - your resolution stays CONSTANT through the play of a deck/shoe - it does not change as you suggested. your estimation (ie how closely you approximate the size of a stack) can change as you get deeper into a shoe.
good though is that you seem to have the resolution concept down...
maybe if im not explaining this clearly someone else with better wording/teaching skills can come in and help me out
