Or am I missing something?
Actually, much of the webbing in use has a breaking strength of less than 1500lb. I don't think the polypropylene straps Clark furnishes have that rating, and many folks re-purpose straps from emergency towing kits with a bs --I'm not confusing it with working strength -- of less than 1500lb. Whether that is smart depends on how disciplined you are in checking the residual quality of the strap before each use.
Breaking strength means "strength under specified conditions and testing protocols."
The hazards to different parts of the system are different. So, you might prefer that portions subject to abrasion, for example, have a higher strength rating. Strands of tree straps wear unevenly, and they are notorious for being cut by hardware connections. Some materials fatigue under repeated or constant use at fractions of breaking strength.
I am sure that the last thing Dutch intends when he builds hardware to certain estimated strengths is to lead everyone to that minimum estimated standard. That makes no more sense than selecting other components not to exceed the hammock makers' estimated maximum load.
