What a great solution for the doubtful! I guess you'll be able to simply direct those who think it's possible to cheat, to these videos from now on.
From my own experience, I've found that I'm getting faster and faster, (as well as continuing to get stuck,) but all in good fun. I've been at it daily for 4-1/2 months now and lately I've been able to come within seconds of the win time (a few of times) which is new for me. So you newbies, just know, there is a learning curve - you'll get there if you wanna. (Of course if you have the time to bang away at cryptograms more than you'll want to admit!)
