I am going to try to do it mathematically and this equation should be taught in all mathematics classes at school!
Here is the formula.
If:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z represent
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
Then: K-N-O-W-L-E-D-G-E can be translated to
11+14+15+23+12+5+4+7+5 = 96%
And
H-A-R-D-W-O-R-K can be translated to
8+1+18+4+23+15+18+11 = 98%. Not quite making yet, hey!
But
A-T-T-I-T-U-D-E translates to
1+20+20+9+20+21+4+5 = 100%. At last!
But wait
B-U-L-L-S-H-I-T translates to
2+21+12+12+19+8+9+20 = 103%
And even move effectively
A-S-S K-I-S-S-I-N-G translates to a whopping
1+19+19+11+9+19+19+9+14+7 = 127%
