I like to categorize backyard courses into a couple of named varieties
Starburst design: one or two baskets, centrally located with walk out - play in to basket. Usually many of the "tees" are off property, out across the street, from a neighboring field, etc.
Spiderweb courses: several baskets, mostly spread around the periphery, but maybe one or two central. A Criss crossing layout back and forth, diagonal. So that if you mapped it, it'd look like a spiderweb with node points.
Crossing fairway links: almost there, but enabled by a (few) crossing fairways. 12-18 baskets, one main routing for a full "round". Maybe an alternate routing or two exists. The rule of thumb for this style is that it could support two, three, (maybe) four playing groups at one time, but by god not a full field as carnage could still occur.
Full meal deal. 9 hole, 18 hole or more varieties. No crossers, and safe for a full field. These are the most rare of home courses. (but also the most epic especially when a special event gets planned)
