BS3 - Refractometer Tool ABV vs Session Statistics Measured ABV?

[chipsalittle]

Just finished kegging an all grain Dead Ringer IPA variation and am having trouble understanding the FG calculations. The BS3 Refractometer Tool calculates an ABV of 6.72%, while the Session Statistics Measured ABV is showing 7.2%.

Any ideas as to what I might be missing?

Thanks!

Just to close this out - I closed and opened BS and the Session Statistics calculation updated to match that of the Refractometer Tool.
