Full suspension - rope strength

[epic1959]

I'm in a situation where I can't test the strength of my rope until I start hanging. Reason being that if it fails, that (quite loud) snapping noise will attract unwanted attention. So one failure risk is that the rope will break. I'm trying to manage that risk. I have a 10mm nylon static climbing rope and I weigh 180 lbs. Anyone have any basic knowledge about weight-bearing capacity of rope? According to the manufacturer the maximum tensile force is 25KN (5100 lbs) and the maximum bearing capacity is 1900kg (4188 lbs). I know that that doesn't mean the rope will hold (or pull) those weights under all circumstances - you have to account for a variety of factors and I am guesstimating that with my body movement it's probably best to discount the bearing capacity by 80-90 percent. So, on the safe side, maybe the rope would hold about 400 lbs of weight? idk - I don't have the knowledge to work out the weight bearing capacity - was hoping someone here does.

That sounds like strong enouigh rope and then some- rope is the 10mm to 12mm range is commonly used.

That rope can probably hang a horse. Knots reduce bearing capacity, but your estimates are way off.

How can you be sure that your anchor point will not collapse if don´t do any testing?

I'm pretty sure about the anchor point but anything is possible.

In what way are my estimates "way off"? Am I estimating too low, or too high?

You estimate that it's possible for that rope to snap before human neck does,
