I've tested this, and I dare say there are too many variables.

Plated VS unplated, Nitros basic or adv or non, as well as level surface or downhill, and even if the HAV in question is on a "tilt" surface (where your HAV moves slightly back an forth on it's own volition) or on a flat surface greatly effects this, as tilt surfaces offer substantial damage reduction and simply "push" you a bit.

Most of the damage is from the LAV detonating and not the impact itself, at least according to tests done with a Saga II running the 60% AND 40% hardeners to better survive impacts.

CCP mentioned a while back that the explosion damage for vehicles is actually a set standard value that deals damage in a radius around the vehicle upon destruction.

Don't remember what that value is, but I do know it isn't a variable

Also, collision damage is still bugged when it comes to tank vs LAV. You can explode from a collision of 5mph because from my experience momentum is not reduced until the vehicle has made a complete stop

I remember when the Sagaris was considered OP with 6500 HP.

Gunnlogi with 5000 EHP already require reloading to kill with the FG unless you can get into their weakspot, and no one who's managed to get a gunnlogi skilled up to 5,000+ EHP is going to be suckered into exposing that long enough to get killed.

given the tenuous state of AV, until the hulls are balanced against the AV that kill them, this is going to likely go nowhere.

Kinda pisses me off. I LIKED hunting marauders.
