Wait a second here. How do you "know" it is right? The SprINT seems to
demonstrate that even well-known experienced mega-contestors still get it

Redundancy is the way to get the message through. If you didn't get it the
first time, how are you going to get the exchange? You have to repeat it.
Redundant. Frankly, I don't see where you are going with this.

You missed the point entirely. Everybody sends 599, so the 599 itself is
meaningless. (Indeed, high wpm guys try their best to shorten the 599 as
much as possible) Since everyone is going to send 599, there's no need to
copy or pay attention to that part.
So, INSTEAD of the 599, we replace it with a two digit "check" value that
can be used to confirm the a) callsign or b) entire exchange.
Imperfect, yes. But such a check would be much shorter than trying to send
the entire exchange twice, but nearly as meaningful. The time-wasting 599
has been replaced with something useful.

Good point about being hard to explain. That would seem to be a point
against snagging those non-contester contacts.
As for the "crutch factor" -- I don't see this at all. I look at it as
replacing something valueless with something of value

Hmm. Lesson learned. Next SS, that crack you hear is me slapping myself the
next time I start to say "please copy"....
