Starting this week I'm adding in standardized review codes.

The letters are mostly arbitrary. Rather they're selected to make it so that creating typos that affects the review mark is less likely. It now requires at least two typos. — Either a place typo and a letter typo or two letter typos.

bp  >   ix  >  gd  >  su  >   er  >  pt
 ⇊       ⇊       ⇊        ⇊        ⇊        ⇊
  3   >   2   >   1   >   0   >  –1   >  –2

Only a –2 is properly a bad review. A –1 just means a standard neutral review. It's negative for one reason: — everything has an opportunity cost. — And everything 0, 1, 2, 3 is basically recommended.
