Looking for input on my extract recipe

Hey Andrew, I meant doing a 60min boil but holding most of the extract until there was 15 to go, not just a 15min boil.

 

I don't know how no gravity vs a little gravity works out, there is a table somewhere in How To Brew that approximates it

I've read and listened to some interesting stuff about the effect of BG on hops utillisation and what I gather is that the theory of BG directly affecting hops utillisation is not actually valid especially for extract brewing. Experiments done with full boil vs. partial boil/full extract vs. partial boil/partial extract and the exact same amount of hops resulted in very little noticeable difference between the 3. My take on it is that a safe bet is to just boil part of the ME but no need to try and target some exact BG - just roughly shoot for a BG somewhere in the range of 1.040 - 1.050.

Sounds like a plan. I gather that you are right that hop utillisation isn't effected by gravity <i>per se</i>, but the stuff that comes with it, and there might well be less "stuff" in extract brews.
