Are team events ranked correctly?

Something that occurred to me a few years back, and again has bumped it's way into my thinking as I'm planning the Pick'n'Mix for later in the year.
Part of the NAF ranking system is based on NAF coaches present in the event:
And I have no issue with that.
But although team events might have high numbers, the potential pool of players is a lot smaller.
For example:
One year, both the ARBBL Open and Pick'n'Mix have 36 coaches.
At the ARBBL Open, I can draw one of 35 coaches. I win the first game, so I have a pool of 34 opponents for round 2.
At the P'n'M (team of 3), I can only draw one of 35 coaches for round 1 (as it's picked on team then coach within team). I also win the first game, but now I only have a pool of 10 opponents (1 coach per team who is in the same position as me within their respective team).
So, should Team events going forward (and historically?) have a K-value based on the number of teams rather than players, or have I missed something blindingly obvious within the whole ranking forumla?
(And before anyone asks, my rankings would take a hit if this was applied in most cases, so I'm not asking for my benefit. )

But I wonder if, for team events, this is correct forumla to use? Wouldn't/shouldn't it be based on the number of teams in an event, rather than players? As I understood it (many years ago, so please correct me if I've got it wrong) the bigger events (i.e. more players) get a higher K-value because it's harder to get multiple wins, as there's more chance of playing someone with an equal (within reason) record than at a smaller event, where that might not be possible.The number of NAF coaches in the tournament determines K-Value in this equation. The formula is:
K-Value = (Square Root (Number of NAF coaches) ) * 2
The Majors have a fixed K-value, regardless of how many are actually in attendance. This is based on 60 coaches, but then double points are awarded. Eurobowl is also now treated as a Major for ranking points.
And I have no issue with that.
