At 2.4% drop in sales and if we assume that for this year this didn't expect a decrease and increase and assume that the normal standard deviation in sales data of 1%. This would mean that we have a 2.4 sigma deviation. As a particle physicist I wouldn't even report this as evidence of a problem. I assumed no increase as a more modest goal after a couple of years of record sales and the current problems in world economy.
