When the rules aren't the same for everyone, it's impossible to judge rankings based on a game by game basis.
For a great example, look at the MtG comp rules. 40k will never be able to support rankings (or 'serious' tournament play*) unless they institute rules of this caliber.
*40k is not meant for serious tournament play, and GWS does not desire it to go in this direction, so this aspect is true, but largely irrelevant.
Of course it would be meaningless unless a standard was adopted for all sanctioned events. The standard used wouldn't matter so long as that standard was consistent among all those who participated.
For our tournaments we use a
INAT FAQ, Book missions and Swiss pairings. Obviously to be valid if we wanted Elo submissions from outside our tournament scene they would need to use that standard to be of any value.
