Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 26. The sections above set out what each side emphasised, in its own terms.

Too few of the outlets on this story carry a published leaning rating to say. 9 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
Is the coverage of Drone strike hits cooling tower at Russia's Kursk nuclear plant biased?
