Ok, I calculate your mash efficiency as 74%. Your brewhouse efficiency will be lower than that by the ratio of Fermenter_Volume / Post-Boil_Volume.

I get your coversion efficiency as 83% - 84%, which is quite low. Conv eff should be 95% or higher. Biggest factors in conversion efficiency are crush and mash time.

Your lauter efficiency is about 89%, which is quite good. This high, no-sparge, lauter efficiency is the result of your very low grain absorption rate (0.041 gal/lb), which is achieved with aggressive squeezing.

Raising your conversion efficiency to 95% would bring your mash efficiency up to ~84%, and 100% conversion would bring your mash efficiency up to ~88%
