It's only 1% - whatever script you're using for percentile ranges is woefully outdated
It might be the reverse, actually. I've noticed this issue recently also, with people telling me their items are 0% but the wiki has them around 50%.
There is always an issue of people not knowing the legendary minimums because they need to be found through brute force. Furthermore, the absolute minimums and maximums are impossible to be found because the PXP0 component makes them rarer. In practice we find the maximums only because of peerless equipment.
I don't use any interface script but as I've been observing the last couple years, I think the ones that people use are designed to purge Lmin data if the equipment is more than a couple years old, even if they are current version equipment.
So the Lmins are rising over time for various equipments, even though they shouldn't be. What I do personally is take the minimum of Lmin from wiki data, script, or whatever equipment I've seen that I know is valid.
Rapier Lmin is one of the few most questionable data though, as the wiki has them really low and the scripts have way higher Lmin. But I still go by the wiki because even if it came from the short broken time period, those might actually be the true current Lmin for a total dud with min PXP0, though we will never see it.
