The big difference between that and the horizontal ladder is that instead of going from rung to rung, you have to take the rung with you and bridge a pretty big gap. I can see how that would be hard. You not only have to jump the bar, you have to get the distance right. I think it would be very difficult.
I always thought the horizontal ladder was a good part of the PT test. I could never figure out what they were actually testing with the inverted crawl though. I never saw any sense at all in that.
“Extremism in defense of liberty is no vice. Moderation in pursuit of justice is no virtue.” - Barry Goldwater
Devotion to the truth is the hallmark of morality; there is no greater, nobler, more heroic form of devotion than the act of a man who assumes the responsibility of thinking.”
― Ayn Rand, Atlas Shrugged
