Measured Efficiency and Measured Mash Eff

Hey Gang,

What is the difference between "Measured Efficiency" on the Design Tab and the Measured Mash Eff on the Mash tab and why are they different?  For me it's 63.9/69.4 respectively.

Yes my efficiency is low and I am working on that, first AG batch, I'm just thrilled I got decent beer out of it  8)

Thanks in advance

Mash eff is efficiency of the mash process.  The other is that but also  includes brew pot and fermenter losses like trub.

I have a dumb question.

What volume do I measure for "measured volume" to allow BeerSmith2 to calculate measured efficiency?

Do I use the post boil volume in the kettle or the volume transferred to the fermenter or some other volume?

Thanks
