RE: sight trouble
I feel that paper tuning has its place. I use it for one thing, elevation tuning. I try to get my high tear under control this way. Left and right tears don't concern me too much so long as they are not enormous. After I get a level tear left or right, I go to group or walk back tuning to do the rest. Works every time. I don't think a 5lb increase is going to get those results.
Group tuning is my bet at what cures it.
