Hmmmm.... I suspect we'll see an official word from FoCal why this method doesn't work so good and we will all read it and collectively say "nice try, bye bye".Sorry to be cynical, but we live in a day and age where people and companies with any kind of commercial interest are known to tell a lot of lies and even defend them in court if it means that they can, well, maximise profit. They might of course really have something, but anything they say will have to be double checked. And although I'll have to do some more tests, as I wrote above, double checking this new method the other day indicated that it was spot on for me.
That was in fact my point... that Focal will issue a explanation of why this DotTune doesn't work but we will say "nice try" to them. You hit the nail on the head... in order to protect their business they will come up with a reason even if it isn't quite true or if it overstates the advantage of their method.
