In reply to BStar:
Serious answer is, in IMHO, that it's probably acceptable, ropes are pretty elastic, (look at elongation %ages on passive body weight, and elongation to failure), probably by virtue of the materials used and their construction (core and mantle, - and they probably exhibit stress relaxation over time), especially if it's being used conservatively at the wall, and the continued use is to be so.
The fall factor involved is likely to be favourable and the ropes are probably 'over engineered'- how often do we hear of ropes failing under normally encountered circumstances ?
I think jimtitt and some of the objective testers will be able to add more quantative analysis.
