custom BeerSmith profile for 5 Gal. BIAB w/ top-off

I am trying out BeerSmith to see if I like it for my purposes. None of the pre-set BIAB profiles match how I use my equipment, so I created my own equipment profile and am looking for feedback. I've attached the BeerSmith Equipment Profile file and a jpeg image.

Here is the jist of my set-up which I hope is accurately reflected in my BeerSmith Equipment Profile:

• 5 gallon Stainless Steel Brew Kettle
• using kitchen stovetop
• 5 gallon paint strainer bag
• I keep my grain bill to approximately 10 lbs.
• after the 60 minute mash, but before the boil, I dunk sparge in a bucket as a means to top off the brew kettle to 5 gallons to compensate for grain absorption.
• after boil and cooling I transfer the wort to a 6.5 gallon glass carboy then top off with enough water to make 5.5 gallons.
• my hope is to net 5 gallons of beer for bottling after fermentation and trub loss.

Are my BeerSmith Equipment Profile estimates on target or way off?
Thank you for any insight you can offer.

I attempted to do this with my converted Keg. I wanted to understand a little more then to use what they had in BS2.0. I still have question such as what is "Top up water for Kettle"? I want to understand BS2.0 but the formas are tough to navigate and I dont get the answers Im looking for.
