It's a little hard to tell, but it looks to me as though there's no real consistency in how the tears read. For me, that may suggest form. While it looks good to observers, subleties like plucking, bow hand pressure, and string finger pressure have a big effect on arrow flight, and will show o the paper tune.
All of which kind of agrees with what Jim suggested above. Maybe not get too absorbed in fine tuning. I'm not preaching here, I'm no expert. I know my tune is as close as it's gonna get, but still see some arrows fly true, and some kick a little. Which. I think, supports my feeling on it.
I tune by sight (and sound) with a fletched arrow, and confirm with a broadhead. Once in a great while I'll paper tune for a little extra feedback.
