When we grade stuff, we give it a percent – from 0 to 100. Then, as much as possible, we have the other person also give a score and we average those together and that is The Official Tangled Up In Wires Score. Then we transfer The Official Score into a letter grade, for ease.
The rubric is below:
98 – 100: A+
86 – 97: A
81 – 85: A-
76 – 80: B+
66 – 75: B
61 – 65: B-
56 – 60: C+
46 – 55: C
41 – 45: C-
38 – 39: D+
36 – 37: D
31 – 35: D-
00 – 30: F
-1 and lower: Don’t touch it! Don’t even look at it!

Tangled Up In Wires 
I love this grading system (although I wish it was used to transcipts) and altogether agree with the grades you two have decided on for most of the reviews. Totally agree with The Office grade for Koi Pond, which has been really below expectations since Pam and Jim tied the knot.
