Confused About Over-Penetration

[navigator37]

I'm newish to the game and need some rules help. Over-Penetration occurs, "Whenever the final penetration value of a shell is greater than 3 times the armor value of a target."
Over-Penetration is listed as one of the optional rules of the River Plate scenario. In that scenario, the max PV would be Graff Spee at extended range while crossing the tee (8+3+1), or a PV of 12. The minimum AV is for Achilles or Ajax at 7. Since 3 times the AV is 21, and no PVs come even close to that number, how would over-penetration ever come into play in this scenario? Am I missing something here?

Nope. Just an oversight on the part of the designer. as looking at the 11" guns on the Graff Spee, and the British light cruisers. . . thought I should throw the rule in. But you're correct, it won't come into play. It's mainly destroyers that will benefit from that rule, and there are none in that scenario.

Navigator 37, Good catch.

Huh. Never ceases to amaze how many times I can read something... and still fail to see something. Nice job.
