People actually filter out some sub grade sets? Like others have pointed out with LC changing the grading, it would be of no use to do backtesting, correct? A C3 note 2 years ago, could be considered a C1 or D1 note now?
Looking at my own backtesting with my filters, just do not see enough difference to actually kick out out a certain sub grade. Maybe if there were more notes available, I could possibly consider something of this nature, as my D3 beats my D4 by almost .7 and just over a half percent on defaults.
I guess that since I am a small fish here, that with less filters, there may be bigger variances.
