Well I just tried the "short unknown" and have come to the conclusion that I'm not as fantastic as I thought[X(]! I tried the sequence at head high altitude to give me a real good reference on holding a constant altitude and wasn't too bad with that aspect but drawing a straight line with all the various points in the rolls was a different story. Sort of looked like the drunk guy trying to walk a straight line in a sobriety test you see on the "Cops" tv show! I will have it mastered by morning.
