As usual on this forum, everyone is guilty until proven innocent. What's so damn strange about someone wanting to study an old hotlap replay? There's still some combos that the wr is not set as "optimal" as in patch X.
Ulisse, the stats and replays from the old LFS version is stored in a backup by Victor. At the moment there's no way to gain access to them, but I do believe that Victor mentioned a while ago he might make them available somehow later on. If you do have some pre Y replays laying around, you of course need an installation of an older LFS version in order to watch them and output lap data.
