How many BA tier points can one be short vs official guideline and still retain status?

I know it's somewhere between 5 and 25 but not sure how much?

Also does one need to call executive club to retain the status (when short a handful of points) or is it automatic?

For instance, obtaining (or maintaining) Bronze status officially requires 300 tier points to be flown in that year. Is 290 sufficient? What's the magic number?

Is the tolerance different for obtaining a status for the first time, vs maintaining existing status?
