If you are, then the bicycle manufacturing industry has just taken, in my estimation, another step into ridicule.
I would be very surprised if 1/8" was an issue.
I was making a general statement about some riders I've seen jacking their shifters mightily towards the heavens because of poor bike fit. This can seriously degrade performance and lead to problems like broken shifter paddles or the inner wires in the housing getting pulled into the levers because the user has to exert too much force to actuate shifts.
I've also seen some damage done to drive train parts because of crappy shifting that was a result of poor or improper installation.
This is more of what I was getting at.
Of course there is some wiggle room with all set ups, and there needs to be, because frames, cockpits etc are not standardized and neither are the people using them - but to a point.
