1:2000000 is also a proportion. Btw, the proportionality requirement in the law of armed conflict relates civilian casualties not with military casualties but rather the military advantage gained. The military advantages of killing a single low-level Hamas combatant are rather limited, and thus the room for civilian casualties should be rather limited as well.
