FWIW when we were trading Minis a good many years back the sales person said the electronic fob stored information about how it was driven and he'd personally had a telling off from his boss for having a bit too much fun in the Cooper S he had as a personal car.
If you want to keep it then I would definitely go by the book - as others have said the Cooper S has always had lots of go so under 4.5K for a bit won't be too hard to manage data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
It's called the event data recorder, in the eyes of the law this is stored and not accessible by anyone other than the police, or the courts, and even then it has to be agreed upon, majority of cars have them and it can't be used to deny any warranty in any case, if you think about it, how much memory would this need over the course of a year and 20k miles if it were used in that manner.
My old Merc - a 2001 model - had the ability to indicate service intervals based on how it was driven so I doubt it's a moment by moment logging of engine speed - more likely like the fault code tables in the ECU.
He said it logged the times the rev counter went into the red which unless you're a racing driver shouldn't be that often.
I hardly ever put our MCS into the red line - there's absolutely no need.
At '05 it is also old enough not to have that kind of data logging ...or a warranty data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
A red line a day keeps the mechanic away.
Italian Tune Up for the win.
