I pulled 12 dead scapes from my plant today. The scapes looked short to me but still averaged 24 inches tall, only 2 way branching and only had a bud count of 7. There were no seed pods on any of the scapes, but I did find 9 rebloom scapes growing on it. I did notice a few of the scapes had the buds forming in a cluster.
I have had this plant since April 2015, so I think it is underperforming currently, maybe by next year it will improve all the stats.
