I hear what you are saying however the whole point of going through the whole 2mm lift / drop method is to make an accurate reading. If you end up with a result that is "about" 0 or 2 degrees there is something wrong. You should be able to get the same result every time within 0.5 degrees - you've got a graduated scale that is good enough for that on the front of the crank.
The thing that doesn't make sense however is that your measurements seem to be suggesting that you've got a shrinking chain. There's been a lot of talk about chain stretch / elongation but there's not much evidence of chain shrinkage...

It does seem unlikely doesn't it?
But there is no harm in checking to see if something is fitted. It would be good to know if there is a key fitted or not.
Note also that the FSM expects about 2 degrees of elongation after 20,000 km - that means that if nothing has been touched for the last 40,000 miles (that's a lot more than 20,000 kilometers) you would expect to have at least the same amount of elongation - may be as much as 4 degrees chain elongation.
I don't trust your measurement - sorry!
