I think your data is incorrect. SGC has graded a lot more than 300 or so t207's. Nevertheless, they are basically impossible in SGC 84 or better.
edited to say I researched it awhile back and there were a couple thousand sgc graded t207's and there were around 30-40 graded higher than 84, with none graded NM/MT.
