i find that it makes for a smoother ride if you add some slack to your descent...
using basesync MFD, i deorbit from the other side of the world, but keep burning untill my freefall path leads about 1/3 of the way too short...
that seems to be enough to compensate for the added lift, which basesync doesn't compute.. this works for the DG... but since it's a very seat-of-my-pants approach, i would suggest some further reading on this particular aspect
then, (on earth) i turn prograde and "button up" the ship when about 200k alt... at some point between 150k and 100k you'll start getting some dynamic pressure... the DG thould reenter at a stalled-wing AoA... from 30 do 40 degs nose up... then hang on for the ride, ad use AeroBrake MFD to guide your ship down, you don't need a autopilot for this... just keep KILLROT on and use the stick for fine adjustmets...
do it right and you should go subsonic just over the target base, with roughly 15k of altitude to maneuver onto the runway...
then just glide 'er in...
