Adjust trub losses for 5g and 10g batches?

[pretzelb]

For those who can do either a 5g or 10g batch in their BIAB system, do you adjust the trub loss estimates for the batch size? I've only done my 2nd 10g batch and seems like I need to bump up the estimates just based on hops alone.

use a hop bag to eliminate the hop issue falling into the trub. Cold crash, whirlfloc tabs/moss, siphon from the kettle while it is in a whirlpool to avoid pulling any hop material/break material etc... that's the only things that came to mind immediately.

I do primarily 5 gallon BIAB batches.

Without a hops bag, I account for about 1/4 gallon lost due to kettle trub.

When I use a hops bag, and filter through a mesh strainer when pouring into the fermentor, I barely have any kettle trub.

Trub in the fermentor depends largely on if pitch fresh yeast or use collected slurry. For fresh yeast, it's about 1/4 gallon or less. When using yeast slurry, I've lost up to a gallon.

I do 10 gallon batches.Average strike water is 14 gallons for a 11 1/2 to 12 gallon post boil volume.I use a hop bag for clean hot break and suck up every bit of hot break into the fermenter.Dont fear the trub.More and more are coming out saying it actually makes for better beer if the trub goes in the fermenter.

I up my batch size to 5.5 for the online calculators to determine full volume boils.
I end up with about .75G of trub/yeast in bottom of primary.
I also double crush to a flour consistency and transfer pretty much everything from BK .

I should have mentioned that the reason I even care is because I'm using a plate chiller. I whirlpool then drain but stop when I start to see hops enter the drain.

The more I think about it the more I think it might be time for a hop filter basket. I was trying to follow the advice of those who just let the hops flow but a filter might be best.
