[Bent Periscope]

I remember reading the same thing. When the number changes to 1.0, it is actually 950m or so.

I read it here (about 1/3 the way down):

I agree with Sharkbit. When the number first change, it represents 50 meters prior to that meter reading and right before it changes is the up to 50 after that figure. Obviously, dead center is the exact 100th amount.

And Yes, I am trying to confuse you.
