Even if tied in overhead; i think that some of these suggestions can make it even safer; perhaps even take larger loads to get out faster. Or, even it is green, safe but 'bouncy'/dynamic etc.; some of these things are easy enough to do; to give even wider and safer comfort margins and productions etc.
As many other things after the patterns are played with and become more familiar; one has more options for safety and production; and can also assess when easy or necessary enough to use; perhaps even speed things along.
i think especially because the first step here is subjective and sometimes impromptu(strength assessmeant); that recommending more options for more totally taking command beyond the assessed risk level is important, especially in Climber 101. i think they are worthy of strategical consideration, as to their net worth of usage per situation.
Rigging thru 2 crotches can take some force off a single crotch and give more friction. It also can change the direction of the force of the single crotch strategy. If this new direction is more inline with the support; the force relief is can be many times more favorable than just the angle between the supports and increased friction suggests; especially on this questionable or dynamic support. Many times you can use that technique strategy to make things safer in many conditions; as well as take more load confidentally. Prestrung just right, even use both ends of the line at different stages, giving 2 separate rigging points.
Especially when the support leverage from the useable axis/direction of the support diameter is not as favorable per the loading force/direction.
