First time using it was a Schildkrote HPPC.
Got Whacked on the side arc a few turns in. Some missile thingy (like a LRM or SRM, not sure but I remember because my AMS engaged and shot down nothing) grazes the hull, gets a motive crit, roll on the table, 12. +2 for side arc, -2 for motive system, so still 12. Bam, tracked Schildkrote.
Jeez! I mean, I know that's a hundred-to-one hit (almost literally, by the probabilities), but still.
You can probably guess my opinion of it.
