normal vacuum

Wondering what is normal vacuum for 86 560SEL. I've been all over the thing looking for any vacuum lines and rubber fittings that need replacing. Additionally had the car "smoked" and the mechanic said I needed to replace injector seals, so had that done.

Vacuum at idle in neutral (around 800-900 RPM) is 19-20. Vacuum at idle in gear (around 600 RPM) is 16-17.

So does it seem reasonable that I've addressed any and all vacuum leaks?
