iirc the track record question was addressed when the tire issue first came up.
As of April, Todd's published position was:
Any track records obtained by tires other than Toyo, will get an asterisk along with the open tire used. Asterisk (*) Track records will be a temporary problem. If we return to Toyo RA1's, the asterisk records will go away. If we move to a new spec tire, only the spec tire track record is allowed to stand.
So, since AI is back on Toyo's, track records earned on non-Toyo tires are removed from the books.
