Does this happen a lot or does it just seem like it do to the writing of the thread?
If you are referring to coyotes making it past one or more sets before getting caught, the answer is yes.
I took a sample of a string of consecutive catches and it showed
seven out of twenty coyotes made it past at least one set.
So, if that had been a single set presentation those seven coyotes would have walked away.
The gang set odds insured they did not. That is not speculation, that is a fact. The numbers do not lie.
