When I asked about a small are similar to this with a sloped ceiling, I was told that since the entire sloped area was encompassed in the remote area an adjustment increase would not be required. But, in this case I really don't know. I know that yould literally reduce the demand area everywhere else except where this pocket is at the least. Therefore if your pocket area was closer to the riser, calc'ing 1500 sq ft may not be as bad.
That is probably how I would look at it. If the high area was less than 32 sq ft, it may be small enough to ignore?
