Well, given the uncertainties of measurements (including pool volume, test kit accuracy, etc.) it doesn't really matter whether you used 5.7%, 6% or 6.3% in BleachCalc since you are going to end up with reasonably close-to-target amounts of chlorine for any of these. The error between 5.7% and 6.3% is only 10% and I don't think anyone is trying to target their FC levels to be that accurate so even though I present the technically accurate information, you can ignore such dribble for practical purposes.
