Thanks for the replies.
For this recipe with this particular hop substitution, you are right to question the need to complicate things - the difference is minimal and probably unnoticeable. However, there may come a time when you will want to make the adjustment.
The big thing to remember is the potential need to adjust the bittering addition and not the later additions...and to keep in mind that some alter additions may impact the IBUs...so you'll need to adjust your bittering addition a second time to account for that.
