This likely isn't a fool-proof method of calculating, but there were approximately 38 days of testing to see 2 billion endurance cycles. It's only been a further 23 days.

My quick maths then would say we're probably going to see results of 3 billion cycles endurance tomorrow. Whatever endurance is mentioned tomorrow is likely the max as otherwise they'd just keep testing.

I'm going 3 billion cycles endurance.

They did state retention wasn't a priority in the previous tests. Maybe these tests were for retention. If so, a 23 day test period would seem a positive for retention results. I do believe retention testing is done in a way that they don't have to wait 10 years to see 10 year retention. There's some process to artificially speed up the degradation to determine expected retention. From what I understand, our lack of error correction should improve our retention also.
