Another thing to consider:
Less than half of top10 have more than 5 elimination counts for ultra-guards, and only two of them above a dozen.
Less than half top50 have more than 1 elimination count.
After top50, you can count with one hand the players with 1+ elimination count for every 50 player set.
I don't think there's more than 100 of those below the top300 line.

This efectively shows a marked failure to confront ultra-guards.
We'll have to wait a full day (a lot of the top300 players are active near the end of the Nutaku day), but I don't really think anybody below top100 will even be affected by ultra-guards at all.
