So unfortunately only got two rounds to go on, but they look pretty good.
1st round-
Dead Reckoning (14) move closer to get better shots.
Dead Reckoning (14) fire on Horrors (53), scoring 312 hits.
Hey, this round is usually just them taking a stroll towards the enemy anyways so I'll take some bonus hits.
2nd round-
Dead Reckoning (14) fire on Horrors (53), scoring 1031 hits.
Dead Reckoning (14) score 802 hits on Horrors (53).
Nice, I was worried their ranged attacks were always gonna be pretty weak. As far as the mediocre melee hits, they have historically as an all-melee unit hit for around 800 the first round before the numbers start exploding in later rounds.
Sorry I don't have more data, but at least there's some.
