    All grain mash ... getting conversion efficiency 101.5% I guess maybe the PPG for malts in the application are estimates, and could in theory be higher, allowing me to get > 100% conversion? Or is this just within the errors of measurement + malt PPG figures?

    Any other thoughts?

    Are you adding any sugars or syrups? That's when I generally get conversions over 100%

    nope... 8 pounds of Optic and a pound of 30L crystal. pre-boil gravity is 1.037 for 7 gallons of wort

    i found the issue... i was using 9 gallons of water and the pre-boil gravity 1.037 for conversion efficiency. But 9 gallons was my total water used in mash/sparge, and i collected only 7 gallons.

    So... my pre-boil efficiency is 77% (based on the 7 gallons), and my conversion number is meaningless for fly sparging..
