Agreed. Coming from a WSM, it seems like (and maybe is) a lot, but it is not out in left field for a horizontal offset. I'll bet with some more tuning (You already did the biggees) you can improve just a bit. Plus, the 'second 4 hours' should be more efficient than the 'first four hours' of any cook.
