One reason might be that the standards for awarding besseae are very high. There have been so many awards lately and what May have been awarded 15, 7, even 5 years ago, is not necessarily awardable today.
It is no one’s fault, it is just the way things change over time.
Naturally we look at size first. Size is compared to the most recent flower quality awards. And I am just picking random numbers here, say 5 years ago, awarded besseae’s had a natural spread of 10 cm. Over the last 3 years, say that changed to 11.5-12 cm. That could cost the candidate a couple of points.
Your besseae has great color, beautiful petals in my opinion, but the dorsal appears a little small both horizontally and vertically.
And the alignment of the pouch is off a little. It leans left.
So it is what it is. A gorgeous flower that isn’t quite up to the most decent AM’s. A point here, a half point here and there can result in a 79 pt. HCC rather than an 82 point AM.
Look at Rothschildianum. The first awards years ago went largely to three or four flowered clones, now 5 flowers are the norm with 6 appearing occasionally. These Roth’s. of today Have greater petal width and greater natural spreads from those of 15, 20 or 30 years ago. I won’t even get into clearer markings and darker colors.
So in no way is your plant inferior, it just isn’t quite up to the current standards for an AM according to the judging team assigned to consider it.
I think I speak for many people here that they would love to take it off you hands! It is that nice!!! I sincerely hope that it gets better with time and one of them gets an FCC!!!
