Mistracking is just a skip that didn't quite make the jump into the next groove. We're talking about differences in degree, not in kind, so any possible explanations apply to both.
I haven't had a Rega style arm for several years (and never had this problem when I did) so I can't advise specifically on where to look. In general, check where the arm wire exits the arm wand and moves past the bearing. Check it at all points across the arm's arc of travel for any pressure or binding. Perhaps Maktheknife or another Rega owner can be more specific.
Good job that you remounted the cartridge. You said your stylus is clean. May I ask what you've been using to maintain it, and how often? I have rehabilitated over a dozen supposedly faulty cartridges costing from $300 to over $5,000 simply by cleaning the stylus properly. The owners all claimed they had done so, but their methods proved to be inadequate.
Just fishin' for ideas that might help...

P.S. Have you changed or altered your phono stage since these tough LP's last played cleanly?
