This would a typical case of what I also find. Why? Let me put forward the following points. Where you hit the nail on the head is it is the same type of queen but it is not the same queen. This sort of thing happens in Europe where I believe they call this type of queen a "blender". Take a look at nature. You have in the race horse industry horses that are better than others. You have humans that run faster than others. So why not queen bees that are better than others? You often find that the traits that make this queen a better queen are not heritable. When you breed from her those traits are not passed on. Maybe it was a fluke arrangements of the genes. They tell me that it is the same with race horses. A lot of those ones that are exceptional do not pass those features onto their progeny. With a bee breeding program, you pick the best but do not confine your selection to only one queen. You pick the top two or three. I remember Wally Maul, from Germany, telling me many years ago in their breeding program that in one case the number two choice produced, on average, better queens that the first choice. On the other hand, you must expect that there will be duds amongst what you get and again this happens in nature. Look at our race horses again. I am not in the game but those that are tell me that there are many horses breed from the best genes available that end up in tins of pet food. I think from what I have seen and experienced myself that performance of queens is close to the typical bell curve. A few great ones at the top, coming down to where the majority are in the middle and down again to a few below par performers at the bottom. So I think that you are looking for small increments in performance and that exceptional one that comes along, as Bob described, are just that, exceptional, and not the norm. It doesn't, however, stop us wondering at that occasional outstanding one that comes along every so often.
