Title says it all, is a used parawing less efficient than a brand new one, as wings are? And if so, how much do they get bagged?
I don’t think parawings bag out like lei wings. The problem with lei wings is that the leading edge is typically dacron and it flexes thousands of times as you pump it. The integrity of is is lost and that results in a floppy or bagged wing. Parawings are better supported by multiple bridal lines and are just made with ripstop nylon or something similar. No dacron. My oldest and most loved brm v1 still flies great after 9 months of hard beating.

A parawing is usually said to be less efficient than a wing of the same size, but given this "degradation” over time of wings, how would a 2-3-4 year old wing compare to a parawing of the same size?
I guess the performance gap closes significantly
