Just did an analysis of the effect of lighted nocks on FOC, using arrows of 20" and 22"s, four different broadheads and three versions of lighted nocks. Long story short: LIGHTED nocks reduced FOC from a low of 3.08 to a high of 4.41 percentage points, with a mean effect of 3.52 percentage points (less FOC).
The highest FOC (17.77 %) was achieved with 150 gr 3" Swhacker heads on 20" Gold Tip arrows and unlighted J nocks, with an overall weight of 400 grns. The lowest, (10.40%) with 100 gr CarniFour heads on 22" BEES and Nocturnal lighted nock. Unlighted J nocks were used for comparison throughout.
Cold, snowy winter, retired, man's gotta fiddle with crossbows somehow.
