Comments of chapter undefined of The Hunter's Mark

Wouldn't increasing magic intensity reduce the requirement of the mark? I mean if one's effective capacity (magic capacity (100)×intensity(3)) is 300, and 80 is required for the mark, then the consumption falls from 80% to ~28%. a magic intensity of 4 would reduce it to 20%, 5 to 16%, 6 to 13%, 7 to ~11%, 8 to 10% , 9 to ~9%, and 10 to 8%. Or does magic intensity only affect deliberate usage?
