I've been starring/adjusting chainline all night. It looks off from behind but on from above. Are my eyes tired or am I just crazy?

You might be crazy.....just kidding. I always look from behind but slightly down at the same time. Many may argue, but it doesn't have to be perfect......mine's not due to putting 1 too many spacers in when I installed the bb......moving the cog 1 spacer either way would really jack it up......I left it and haven't had any problems in many miles...I'm interested in other's opinions on this also.
