Yeah, sure but here the fact is that the run was bugged, so even if this bug has been added to the rules after, it's still a bugged run. So even if the rule wasn't added, this run has to be deleted long time ago if someone saw it before.
Regarging the 1.5XS and WPrime 1.55, no we can't delete these entries that are older than the rules.
Unfortunately (I haven't managed to beat WPrime 1.43 scores even with higher frequency)
