Not sure about MVA levels (anyone know one of Bill Gates' phone numbers so I
can test this?), but everything I've done from a  230 va obit to 50 kVA
(actually was closer to 55 before the breakers popped and the utility and
neighborhood complained) the 3.3-3.5 kVA/foot rule applies. In think the
catch is to increase voltage along with current. With a 14.4 kv pig,
increasing current much beyond an amp actually stops the arc from climbing
as high up the ladder. Not sure, but seems to be blown out with its own
magnetic field before long once it starts. I got around 17 feet with 69 kv,
~800mA. Unfortunately I sold the pigs when I moved from Stanberry MO to here
in Cincinnati a few years ago. (The (2) 34.5 kv 25 kvA pigs weighed over
1000 lbs each, not something easy and cheap to move if you have no garage to
put them in). I'm guessing as long as  the voltage/current ratio is around
1A/50kv or so and a huge air mass was perfectly still (unlikely when
measured in  miles) it's close to linear.
