This motion arose out of member feedback. In one case, the player in question has health problems that prevent him from playing 5 rounds in a weekend Swiss. In the days of his having better health, he accumulated 2 norms and missed out on a third. This last being an exceptional result over 4 rounds that, due to his health, could not be stretched further. Of course, back then, the program was not in place and his playing strength and ability to fight through the pain to attend events in general has fallen since.
In the other case, the player had a norm result after five rounds of play. Had he withdrawn, his norm would have been secured and, in fact, would have counted for the category above the class in question. Instead, he played on in an attempt to continue his winning streak. Again, this was during a time when the program was not in place, and he ended up with a perf slightly below the floor.
That's the context, for what it's worth. I believe we may also eventually have a request that a norm result over 10 rounds be counted as two norms.
