Bevo,

I would assume those stopping numbers for the F-4 would be for the original full TE flap config with functional TE BLC. Steady tone touchdown (impact) approx 135-140?

The USAFR & ANG Phantoms quite early had the TE BLC capped and TE flaps limited to about 1/2 travel IIRC for MX relief reasons. Most people flared (not all, some diehards still planted it) them 'normally' from IIRC about 155 if on speed. 4000' for a no chute would be optimistic I think, even at sea level for the modded ones.

Generally 2 reasons to no-chute, unplanned a malfunction, here full anti-skid braking may be necessary....or as TTN says planned to avoid the usually unpleasant task of self installation away from home, although for F-4s, Transient Alert at ubiquitous F-4 bases were of course trustworthy. (Worst drag chute installation was on the F-100 and those days away from home you had to do it yourself)

Runway and conditions permitting, our rule of thumb for planned no-chutes (gouge applied nicely to all three F-100, F-105 & F-4) was to stay off the brakes until below 100 KIAS and then you could lean on them and you wouldn't get hot brakes. We'd no-chute into Miramar and never got turned away at the Octagon hot pits for brakes.

(But you were taking the chance that you may end up wishing that you'd got on them earlier, but that's what tailhooks & BAK 9/12s are for.)
