Slippery slope but if it's dead in between then it's half in each coverage area so the "miss" per sprinkler is in fact half of it, in my opinion. At the end of the day it's not as though that shadow area isn't getting wet, it's just not getting .1 or .05 gpm/sq ft wet. I'd try real hard to avoid it, but I wouldn't lose a lot of sleep over it if that was how it had to be.
