proper idle speed

[ars14]

Hey all, I was wondering about idle speed. I see that it should be between 600-800. but my tach seems to be below the half mark from 1 to 0 a little above the first mark past the 0

?

I think the mark you're reading as the "half mark from 1 to 0" is actually the 750 RPM mark. The first mark past the zero is 500 RPM.
