I had read on other boards that SGC was thinking about adding more half grades to their grading scale than they have now (20=1.5, 70=5.5, 86=7.5, 92=8.5).

It looks like they have started implementing the new grades - I just looked at the pop reports today, and I noticed the addition of the 35 grade(2.5).

So, are we to assume that the grades of 45 (3.5), 55 (4.5), and 82 (6.5) will be added too?
