Extract brew steeped grain absorption volume

[stevebonny]

I was at my son's house for his first brew. We did an extract wee heavy in a small (2.3gal) batch size.
We ended up short of pre prepared water by 0.3 gallons.
Probably many reasons this could have happened an I should have had some spare water on hand!!
Anyhow while investigating the error, I noticed that the software doesn't seem to take account of the steeped grain water absorption volume.
With our recipe it would have been about half a pint.
Is it just considered negligeable, or should it be accounted somewhere that I'm missing? Thanks.

Did you squeeze the steeping bag? You can get a lot of that back by squeezing.

Most extract lit instructions call for topping up the fermenter to reach the specified batch size, so they don't account for grain absorption.

Oh yeah, no don't think we did that! Thanks.

Yeah, it could have been an easy fix if we had extra water on hand. I somehow messed up preparing the right water vol, thought I had some spare but not the case. We could have dumped a little tap water in to fix it, but we voted for a slightly stronger brew!!
