I calculated this here few days ago

Markus Weber from KPN is generating a daily report here and drew similar
conclusions: https://as286.net/data/ana-invalids.txt Markus scrapes all
routes from the AS 286 PEs and marks the routes for which no valid or
unknown alternative exists as "altpfx=NONE".

Or delete the incorrect RPKI ROA. Either way is fine.

Perhaps the RIRs should start an outreach program to proactively inform
the owners of those 2,200 invalid route announcements to get them to
either fix or delete the RPKI ROA.

Kind regards,
