How to improve my efficiency

[mjs3]

I thought BIAB was a no-sparge technique, which is why you take on efficiency (I also would have guessed that 62% would have been pretty good for BIAB)...I'll defer to the BIAB experts to correct me.

I just use a bag to make cleanup as easy as possible.
I heat my sparge water first and set aside that kettle in my 175 degree preheated oven..
I use my normal amount of mash water and add a cup of sparge water at a time if my mash is too thick.
this plus step mashing has helped me see up to 80% efficiency.
