Since when are we only talking about these mistakes? Which post am I supposed to
re-read? I've been reading this one:

http://www.icdchess.com/forums/1/message.shtml?198458

and it doesn't qualify the word mistake anywhere. Instead of calling my reading
skills into question, how about you be a little more careful when presenting
your points, eh?

As for your whole consistency argument, you are working from the fundamentally
flawed premise that if a shallow search can't identify a mistake, then a
somewhat deeper search can't either. Let's say you make a mistake at move 10
that a shallow search can only identify at move 11. If you analyze
front-to-back, then yeah, you will consistently identify the wrong move as a
mistake. But if you analyze back-to-front, then there's a chance you will
identify the actual mistake as a mistake, right? So let's just get this
straight, you are saying that being consistent is worth more than increasing
accuracy? Some would beg to differ...
