I'm saying it's got to be significantly higher than that (or else what's the point in a lot of cases?).
Thanks.

Ah! I love these questions - - bets!
The answer is - IT DEPENDS.
Each seat will have its' own ejection envelope.
Speed at the top end being one defining feature of that envelope.
So in my opinion - neither of you win because it is too broad of a question; BUT - if I had to say one was more correct than the other - I'd say "the other guy" gets the nod only because of survivability.
There was a Replacement Pilot who ejected out of a Hornet back in late 2005 down around Key West. He was too fast at the merge for his own good, went vertical (down) and blacked out. Came to once the G was off, but as is often the case disoriented. Didn't know where he was but saw nothing but ocean and decided to eject. I believe he was MORE THAN 500 kts indicated at the time. He survived but was basically a Raggedy Ann doll with limbs hanging on by a thread when they fished him out of the water
NACES seems to be the most plentiful seat out there in my former community and I believe that 600 kts was considered the top end of the envelope, with betwen 250-350 being the ideal ejection airspeed - but it has been awhile since I looked.
