You are right. When all else fails read the manual, right?
According to the manual, all that is required is for the throttle to be constant during the shift. It says any change in throttle position during the shift can cause the shift assist to "abort" or the shift to fail.
By blipping the throttle, I was changing throttle position. My bad. It can be closed as long as you keep it closed through the shift.
I do agree that once you learn to use it right, it is an amazing feature.
I had read the manual, seen all the posts about it on the Forum and spoke to my dealer about it. He was of two minds - that either mine was defective (which would be the third defect on my R1200RT; the shock, the alarm failed and then the shift assist) or that it was out of adjustment in that it wasn't picking up on my initiation of the shift. I got it to work about 75% of the time - always with constant throttle, never blipping. The GT OtOH shifts smoothly every time!
