"You might want to take a look at QST magazine tests, both for your rig and others,"

I don't think you're going to find their rig in QST ;-)

Not the point.  

What they WILL find by checking out even a handful of past QST rig tests, paying attention to the always-included 'scope pix of the first QSK keyed character width, is that they will be hard put to find ANY rig that doesn't truncate that first character.  

Some are better at it than others, though, delivering a little bit longer first dit length, maybe there is one out there somewhere that actually can make the full dit length in QSK mode, don't know, it would be one of the exceptions rather than the rule, though.  And that's the point.

>My 62 mS timing was something I measured myself, not depending on someone else's formula. I think the formula is off by 2 mS. Can you prove otherwise?

Yes.  PARIS (and the space after it) is 50 elements (you can count them).  Thus 20 words is 1000 elements.  One minute is 60 seconds, or 60000 milliseconds.

60000 milliseconds/minute divided by 1000 elements/minute gives 60 milliseconds/element.

I have been suspicious of the accuracy of the speeds for some keyers.
