Abrasivity index for new toothpaste?

Dear RDH eVillage:

Does anyone know the abrasivity index for Crest's new Pro-Health toothpaste?

Director's note: The exact abrasivity index number is often proprietary, but Procter & Gamble did provide me with the following response: "Crest Pro-Health toothpaste is consistent with industry standards — its RDA value is below the 250 maximum safe level."
