Welcome to the forum. Still no replies so I'll give you my rookie perspective (1 year experience and I've shot 1 coyote)
What you posted for the most part sounds textbook, better than my stuff to be honest.
This place you were calling, do you think other people are calling there too and the coyotes are "educated" to people coming in with e callers and know what you're up to? Was it fairly out there where other callers probably aren't going to? Or just off the road nice and comfortable for you and others?
Also something I got from a dvd is the narrator described a coyotes life as similar to living in a prison without groceries and all the cells are open door. No free or easy meals and life is rough. Territory is everything. And his calling sequences were based on invading the coyotes territory, announcing yourself as a stranger coyote, portraying yourself as eating the food contained in that territory, and then letting it be known you're a beta or weaker coyote.
This made me think, if a person was brand new in a prison, and started hanging around a groups open cell block who he did not know, suddenly their instant noodles start going missing, and this new guy starts showing signs of weakness...things are gonna go down in a hurry. it's a very different vibe and much more intense and urgent than letting it be known there's ramen soups around in the other side of the prison in possibly some other groups cells/turf.
Or imagine you heard about a thief in town stole someone’s tools. How would you react? Compare that to a thief coming into your backyard a going thru your shed and stealing your tools. And when you look at him he’s a scrawny wimp who couldn’t punch his way out of a wet paper bag. Same reaction?
Now getting inside that coyotes territory up close and personal without alerting them…
