or maybe the difference in dollar amount between using 50% or using the 36 to 45% based on the formula that I am using is not significant. Using 50% of grocery bill for me in 2015 would be about $7,700 and using the food consumed by dck formula is about $6,400. Maybe that does not make a big difference compared to what they collect everywhere else and the auditor can just give it a pass or just make a recommendation to improve the calculation in the best case scenario.
