I got 141 and 145 the next couple of times.

The fastest is 247. I think they probably used a program for it. I think you could likely set up something on easymacros pretty easilly.

Type the alphabet and tell it to repeat say... 150 times as fast as possible. (15 character maximum with 10 words per round)

I may give it a go later.

What is it they say about silence being golden?
