Just wondering how Blood Lust / blood tokens work.

If I injure someone and gain a token, the rulebook states my Star Power increases by 1.

Is this just for determining who wins the match-up at the end of the round, or does this increase the Star Power for tackle attempts etc during the match-up as well?

Rule… pamphlet says blood token increase Standing and Downed star power. I took this to mean it increases both for tackle attempts.

Rulebook makes it a point to mention that balls don't add their star power to ball carriers during tackle attempts, so I figured that they would have said the same thing about blood tokens if they wanted them to function the same way.
