Soz,
That is one of the best ways to evaluate a riddle. I once wrote an essay on creating riddles and evaluating riddles. I will rewrite it one day and post it.
BTW, when you said it was not math it was obviously letters but determining the letters is a tough task when you do not use a 0 before the single digit letters, more importantly it's tough in a tedious way, not in a degree of difficulty way. Just a minor gripe (which I don't have the right to, if anyone has a right to gripe it's TGR who spent time trying to solve it).
If you like this type of riddle I know a few really good ones and I can make up some impossible bad ones.
