I've noticed recently that on some segments there are some athletes that have two efforts shown, from different years (one example looks like this: 1.A in 2021 2.B in 2021 3.B in 2020 4.A in 2020 ... 9.C in 2021 10.D 11.C in 2018). The rides are not marked different (ride/mtb ride) and the profiles are the same (same url).
Anyone knows what this is about?
