limited experience here, but i would say that i can't believe how little misalignment you have. Especially if you started at one end and this is all the diff about 17+/- feet later. a testimony to your skill and care and the panel offsets and design.
2 quick swipes w/ some sandpaper and y'r laughing. makes 0 diff right at the ends with such tiny discrepancies.
next time wait until there's a problem!
