The other thing to remember is that the data retention time is specified as something like 10 years.

After exceeding the number of write cycles the retention time will be less.

A datasheet I read years ago did point out that the locations that are frequently written are unlikely to be the ones on which you need long retention times.

So engineering boards - where you don't care about long retention times - are likely to 'work' after a lot more write cycles. Just don't send them out to customers later.
