Just be sure to account for the difference in hop utilization. Utilization is dependent on the gravity of the boiling wort, so your pre-addition boil will utilize differently than your post-addition boil.
You can use some brewing software to help calculate the differences or check out some hop ultilization charts online. Palmer has a utilization formula in "How to Brew" and Papazian has a few charts in his book as well.
this is currently up for debate on this forum and among the 'scholars' such as Palmer, Jamil, and Papazian. it may have to do with gravity of wort but it may also have nothing to do with that and entirely have to do with boil time to get the hop oil isomerized. check this thread out: http://www.homebrewtalk.com/f37/hop-...e-late-247665/
