Here is the Carnage Count. They are a little lower because they missed a couple of kills, but also they understandably did not count the number of time Strange died. We counted it because the memories of the event stayed with both individuals, so while that moment occurred repeatedly, the deaths are still valid unlike the deaths on earth where time was just rewound rather than relived.
This kill count counted the deaths of strange at the end as well as a civilian death that did not actually occur, though they missed quite a few others.
