Subject: [Leica] Focus, Noctilux, M8, C Mode & Scotch

I would like to follow Ted's advice and just take this Noctilux  
everywhere, but I am having an issue with focus, and I don't know  
whether it is me, the lens, the M8, or all three.

The lens seems to focus slightly beyond where I think the focus  
should be.  I am using the 1.25x eyepiece magnifier to help, but it  
still is there.

If I try shooting at a ruler, at the closest focus around 3.5 feet,  
the focus seems to be maybe 0.5 to 1.0 inches beyond the focus I  
set.  (Of course, when hand holding I am probably swaying more than  
that.)  With the shallow DOF at f/1, this is enough to put an eye out  
of focus.

I have tried using the C mode when shooting at f/1, and fire off a  
series of exposures while I ever so slightly rotate the focus further  
away.  This actually works, and almost guarantees that one of the  
exposures has the focus I want.  It is not really how I want to  
shoot, however.

Another embodiment of the C mode method would be to first have a  
drink of scotch, focus, and while shooting a run of exposures sway  
forward slightly into the scene.

So, what are your thoughts?  Should I:

1.  Send the lens & M8 to Leica for a checkup, and forget about the  
camera for two months?
2.  Send the lens & M8 to someone other than Leica?
3.  Just send the M8 in for a checkup?
4.  Just use the C mode method?  If so, which brand of scotch do you  
think would work best?
5.  Send myself for a checkop?

when the government's purposes are beneficent. Men born to freedom  
are naturally alert to repel invasion of their liberty by evil-minded  
rulers. The greatest dangers to liberty lurk in insidious  
encroachment by men of zeal, well-meaning but without understanding.
