Thank you! Very nice of you )
About width - very agree with you and others that it's counter-intuitive. Myself always falls into E / F trap. Yeah, the point really was about hitting 2nd and 4th columns more frequently, but also make 1st and 5th column hitting less frequently to round up "probability" of cell hitting. Though your idea about bold vowels don't come to me, it's really clever. I'm glad that my game made you so involved ))
