based on many comments in this thread your statement is not accurate. for example my iphone 15 pro is at 83% with 654 cycles. clearly it will drop below 80% in less than 1000 cycles
The bar clearly won't be "any random person's phone meeting this criteria", so what your specific phone does doesn't really matter.
it will be seen how the actual requirements will be validated, likely in a way that favors the "best case" scenario for apple.
