I don't know if the relationship can be described that easy, Mark. But you right, the edited fuel flow might have to be edited again if CS increases the drag component.

My problem isn't the overall speed of the bird (it's a powerful one, no doubt) but the too fast acceleration after TO and with gear and flaps going up.
Normally, setting climb thrust and pitching the plane up will establish ATC approved speeds but on this one, it all happens too fast from e. g. 180 knots to 300.
I can't remember any B-52 videos where the engines where throttled back that much together with a need to pitch up by such huge amounts.

So an increased drag should hold back this fighter like acceleration tendency in the sim, not more, not less.
The later climb phases look good to me, the initial 10.000ft are the problem in my eyes.
