If results differ, then the investigator needs to obtain unadjusted data from either the data service or by hand-collecting all or part of the split-rounded observations potentially affected by rounding error. Another approach is to obtain individual analysts' forecast data that are not rounded and compute the consensus forecasts more precisely than two decimals.
