Mechta,
LOL, yes I can imagine, it's been a long time since I flew gliders but I am pretty sure that no one ever kept a track of how many launches a weak link did. Would be pretty hard given how often the link gets changed for a different colour when there are several different types of glider being launched.
On reflection I wonder how many weak links last as long as 200 launches and how many clubs routinely replace all of their weak links.
