I know the exact post you are referring to, and when I tried plugging in the numbers, the DR_MULTIPLIER never even hit .9. My ghost acres multiplier for several attacks in the above scenario is around .65-.7, and actually doesn't appear to be affected by oversending, though I only did that once and the result was virtually identical. Further, my raw acres has been literally unaffected, as I'm able to predict that with 99% certainty when boxcar identifies DR as <=1 (possibly 2, haven't checked that), assuming 95% perfect NW match which as per the forums is .068*TargetLand*MilStrat(*GovBonus for Tyranny, though I haven't tested that).

So it seems that the DR formula is different for raw acres grabbed and ghost acres. Which is why I'm inquiring here. Or I'm making some other simple mistake, but what you suggested doesn't really clear up my problem as far as I can tell. Maybe you/someone could be more specific?
