The recently introduced Marshal badge is awarded for achieving a flag weight of 749. According to this investigation by marcog (meanwhile confirmed by Wladimir Palant), it takes a mere 10 correct flags to get from 749 to 750, so why isn't the badge awarded for reaching the maximal flag weight of 750?
To make this clear: The original intention was to make 750 an asymptotic limit that can't be reached (except due to rounding errors maybe). If that was the case, then the 749 would make a lot of sense. However, the actual implementation is such that the increase in flag weight is always at least 0.1 for each correct flag on questions and answers. Thus, it turns out that the limit 750 can easily be reached, even without any rounding issues.
Just to point this out before people start telling me: I don't even know what my own flag weight is at the moment.
:-)But thanks nevertheless.
