Your numbers add up.
What's the top up water for kettle for?
Do you find that you are quite often over gravity or under volume before the boil, hence the top up water?
What's the Lauter tun deadspace, 0.5lt?
Your 4lt loss to trub & chiller is what you leave behind in the BM after transfer?
The 2lt is obviously whats left behind after fermenter transfer.
Do you find that 72% efficiency is where your at?
Can you post a profile of the 50lt pipe as well.
I'm starting to think my profile needs some tweaking.

Your numbers add up.
What's the top up water for kettle for? I think it is for extract brewers typically, so for AG brewers unlikely to need to do this.
Do you find that you are quite often over gravity or under volume before the boil, hence the top up water? My numbers work for me for a 60 minute boil so i don't need to top up often. I forgot to mention in my equipment profile that if I do a 90 minute boil I add 2.5L to compensate: in this situation I take a pre-boil gravity and adjust accordingly, typical that is 2.5L (the additional boil-off).
What's the Lauter tun deadspace, 0.5lt? Buggered if I know, guess I got that figure from someone else profile. I don't think it is material.
Your 4lt loss to trub & chiller is what you leave behind in the BM after transfer? Yes I lose a lot to trub, but always get crystal clear wort. I think I might need to play around with the amount of kettle finings to I add to reduce this. Just adjust this figure to what you leave behind e.g.. 2L.
The 2lt is obviously whats left behind after fermenter transfer.
Do you find that 72% efficiency is where your at? Yes that what I typically get and the lower efficiency is largely driven by the trub losses.
Can you post a profile of the 50lt pipe as well. Done
I'm starting to think my profile needs some tweaking. I think it could be improved. However like to said you hit your numbers, but I suspect the your boil-off rate is probably a little high, but is countered the fact that you don't have a loss to trub in your system profile: in this case two 'wrongs' have made a right. But when things don't go to plan as happened in your wit then things can get confusing.

Thanks mate.
I've done a bit of tweaking for my next brew day & I'll see how the numbers stack up.
Cheers

Just a little update on this Wit beer.
OG of 1.042, FG of 1.010 so ended up being 4.2%
It's my first ever Wit & it's a great beer. It finished quite dry & it's pretty refreshing. Very clear with a super tight bright white head & nice carbonation. This will be an absolute cracker come Summer when the lawns need mowing weekly. There's a slight hint of Coriander & bitter orange peel but ever so slight. The yeast, WLP400 is obviously the star & that's held true.
It's simply a great session quaffer that I'll brew again for sure.
