Where should "white N9.5" chip appear on the WFM (what IRE value)?

Attached is a spreadsheet that X-Rite sent me in response to my request for specs on their ColorChecker Passport Video. The spec of the brightest white chip is N9.5. Properly exposed (or adjusted in post), what should the corresponding IRE level be on a waveform monitor?

Because the 18% gray chip is labelled 40 IRE I assume there's an equivalent IRE level that the N9.5 chip should reach. Am I wrong?
