That would be 12:1.

 

The stepped/ tiered config for pulleys, limits movement more; than if pulling dual pulleys or pulleys to drop eyes of other pulleys etc.

 

For tree force levels, and not using tree as anchor, would place a support leveraged higher in equal / opposite direction of rig pull to another anchor.

 

Can '2 Hand' rig for more input force.

 

Anchor parts like green webbing would be leveraged less if 'teepee' was not so flat, or even to 2 eyes of end of sling. If pulling to upward (or downward) angle, would make sure at least 1 turn of green webbing was seated to spar/ anchor in front and not to loading pull.

 

In end when goes to tie off, should seize fast where doesn't spread apart, then give to Half Hitches. Halves have better/more contact area than fig.8 as stop. 1st half should seat square to stop, then 2nd same behind to keep first fair and square. Fig.8 looks like better stop, and does have more weight. But bulk of fig.8 is not where it wo8uld be stop, and the stop side has open side as leads to fig.8 bulk.

 

When he is binding the spreads apart, this is giving more tightness, and would finish doing that, rather than leave spread.

 

Nice barefoot walk though!
