Star System Level vs Multi-Stellar vs Low Galactic

You may notice that the OBD and vs battles wiki have two entirely seperate definitions on what qualifies as solar system level and galaxy level, OBD also having "Small Galaxy Level" while vs battles wiki also has "Multi-Solar System Level".

OBD's values (which is what I'm used to using)

Solar System Level: 5.709 Foe (1 Foe = 1 Supernova)
Small Galaxy Level: 10 KiloFoe
Galaxy Level: 10 GigaFoe

VS Battles wiki's values 

Solar System Level: 22.77 Foe
Multi-Solar System Level: 20.08 TeraFoe
Galaxy Level: 10.53 ZettaFoe

You'll notice that the values are incongruent to the point that vs battles wiki's definition of multi-solar system level is over 20,000 times that of obd's wiki's definiton of galaxy level. This is not actually a math error and moreso a difference in interpretation over what destroying these things mean.

The OBD's definition of these things come from this paper suggesting the binding energy of the galaxies, the energy required to acclerate it's mass past it's own escape velocity and similarly the mass of the solar system and it's escape velocity.

VS's battles wiki's definitions come from these calcs on how much energy it would take by inverse square law to destroy a planet at the edge of our solar system (or Neptune's position) or to create energy to destroy a star at the edge of the galaxy from the center.

In essence throwing 10 GigaFoe at the Milky Way would destroy the stars in the center of the galaxy and would be enough energy to send all the rest of the stars away from it destroying the galaxy as a unit whereas throwing 10.53 ZettaFoe at the Milky Way would be enough to destroy all stars in it. It's a semantic differnece in terms of what "destroying" a galaxy means.

Personally I use the former since it seems to be more consistent in my view with the widely accepted definition of a planet buster being someone who can accelerate the mass of the planet Earth to it's own escape velocity and thus overcome it's GBE rather then the more violent destruction of like taking the inverse square law from the center and destroying metal at the edge of the Earth.

Especially given the discovery of even smaller galaxies like Segue 2 which could require as little as 1 KiloFoe to accelerate the mass to escape velocity, I don't really see the purpose in Multi-Stellar anymore (assuming you are using the escape velocity values rather then complete destruction values), and think I will just use the term Star System Level to refer to anything exceeding 5.709 Foe and is below the KiloFoe range. Especially given that Star Systems can vary in size and ours arguably goes far part the Sun-Neptune or Sun-Pluto range, I think this is a pretty fair wiggle room for the level.
