Location: Indonesia | Advantages and disadvantages of each method in my opinion:
Method 1
+ Completely specifies each row/column
- Difficult to remember the 6-character legend
Method 2
+ Simplified version of Method 1
- L appears twice as often as I, making it somewhat guessable
Method 3
+ More consistent with other shading answer keys
- 1 and 2 can't quite differentiate I's and L's
Method 4
+ Centers are not easy to guess
- Probably difficult to notice
I myself seem to prefer Method 3 slightly, with Method 2 coming second. |
