Asking if anyone has figured how to use SCO similar to the 7 second/75% rule when near a target in supercruise?

Right now when I use SCO to cut down long trips I either overshoot and Loop of Fame (not a typo f** shame in all situations) it back to 7 seconds from the target or shut it off further than I would like.

  • Or does anyone know the minimum distance or time to hit the brakes to get as close as possible?
