SAC criteria is not a cost saving measure, it is put in place to prevent overruns etc. but I won't labour the point because every professional pilot on here already knows that.
To those saying energy management lack of flying skill etc as to reasons why approaches such as this are not dangerous, well just because I can doesn't mean I should. In facts spooling up at 500' isn't something to be proud of. Sometimes it happens sure and the approach is just about stable, but 500' is a limit not an aiming point for being stable.
