For hinging in general i've studied all my cuts i could before/after and any i could try to decipher of other's cuts forensically.
.
i try to see/ examine in regular felling, cross compair to climbing and heavy bucking.
i think in heavy bucking top compression, most severe compression is to top/12 noon,
so favor 'swing dutchman type fold to about 1.30 on the clock, dutchman going to top like it was the heavy side lean pushing to 1.30 as less severe force etc.
But work to show all principles work at bucking and cutting aloft angles and still hold true.
.
Also, a favorite examination is with the preciseness of the handsaw while climbing or even some on the ground.
Perhaps cut small face with chainsaw, mebbe even start backcut. But can finish face/ try bypasses, finish back cut and fold by hand.
In right ranges, can even find something that doesn't work, open face up and adjust and pull again.
"Feel" and know the resistance. Especially in the question of vertical bypass vs. horizontal dutchman i've seen/felt the difference in these smaller scales and expect principles to carry to larger scales and seem to see same thing. Horizontal dutchman seems to give stop, where vertical bypass seems to give interruption to fold, but can keep going mostly.
.
This is the logic/pictures i putt to it, to imagine it as i carve, and stay within rules, give each action and inaction purpose to target and models to make intuitive that i've thought in. i try to show/distill to what i think is important base principals, for in most things find real powerful tricks just 1 step above clean basics! i know i say some controversial stuff, starting with being new guy on ISA bbs in 90's and saying climber self-lift was 2:1; but in all humility,must honestly claim a rather strong score of being 'spot-on'.
.
i have no clinical pruf, but this is what i believe i've decoded from what i've seen; the best i've been able to 'draw' them out of me.
i believe i've seen scant references to horizontal dutchman worser than vertical bypass from others over time as well.
