Four sets of string tests showed a blatant small grouping between 43gr and 44.5gr.

Tests at 43, 43.5, 44, and 44.5 with 0 jump .01 jump and .02 jump also showed obvious winners of 44gr and 0.010 jump.
Now that you did your big steps of 0.5gr, push the cardboards further out to 300 or 400 and do 0.1gr steps within the range you found the big sweet spot.
