The notes to the GAC tables in the LQM report typically state either: "Values are rounded to two significant figures" or in some cases, "Values are rounded to one or two significant figures" But the values for many of the GACs are quoted to 3 SF. Paul - can you clarify whether the numbers in the tables with 3 SF are to be used as stated or should we round to 2 SF, as it is clear that a lot of the other GACs have been rounded to 2 SF. And how have you been rounding: up, down or closest? And under what circumsatmces is 1 SF to be used. Cheers Chris Dainton
