| I'm with other's on this; while mathmatically the 1,2,1 makes sense, it's just more intuitive to see every square as 1 and not think furhter on the subject. I don't ever have to wonder whether or not reach hits here, or a blast hits there. It's really just about keeping it simple; and I never thought the 1,2,1 was all that simple.
However, if you've trained your self to see the grid that way, I can understand the headache about unlearning. Simple answer, do as Yoda says, "Unlearn what you have learned." |
