So I did this a while back when had dimensions and specifications from the Bunyan-al-Marsoos event. Take this with a pinch of salt - I used a ballistic simulator that I made with all the numbers I could get and then assumed some ballistic coefficient and burn time numbers that agreed with tests that we saw. I am basically assuming F2=SMASH. I have faith in this but you don't have to.
Ok so pure ballistic launches - no maneuvering. I swept through various launch angles. Three vertical red lines where first line corresponds to impact mach of 1.3 - like in the video we saw (first or second test) and the remaining two are 400 km range solutions both of which are >2 impact Mach

Also measured the impact angle on the F2 test...42 deg

Notice the impact angle on my plot 38 deg maybe? for the first 1.3 Mach impact
so very likely they tested F2 at 250 km range, but it validates all of the aero and controls.

It is capable of M>2 at two trajectories:
274 seconds. The second vertical line in the previous plot. Depressed trajectory I guess. Doesn't even go to space (above 100 km)

448 seconds. The third vertical line in the previous plot. Lofted trajectory. Goes to space. Comes back at a steeper angle and higher speed

The main point of all this is to show that you can do this test:

and this will essentially verify all of your numbers for you. Now you know with some certainty you can use this missile on the 400km trajectories. Obviously, you wouldn't start with the 400km tests because its difficult to get targeting and set up exclusion zones. But you can verify your model, which is what is done.
