100% for the snares that I caught a coyote in.
It's pretty complicated for me to figure out but I'll give it a shot.
One week of 10 snares, two weeks of twenty snares and four weeks of 30 snares (approx) gives me an average of having 21 snares/week for 7 weeks (without mentioning the snares not replaced after a catch).
I've caught over 30 coyotes, so, 30 / 7 = 4 coyotes/week in 21 snares = 20% (approx).....I think.
My brain hurts, I need to lie down.
