If you gave every freshly minted cfi or commercial pilot a straight forward ACS/PTS 709 ride today what percentage would pass?

I am confident I would have passed a month or 2 after the ride. Now having not touched a single engine plane for close to a year and being an airline pilot…. The outcome would be questionable to say the least 😂 I renewed my cfi with Efirc last summer. I plan to keep doing that for the hell of it. Hypothetically if I had to do a 709 for whatever reason I’d just say nah yall can keep it lol. Not worth the effort
