Unit test that fails:

    testGetAvoidanceAfterDR = function()
            --[[
                avoidanceAfterDR = GetAvoidanceAfterDR(avoidanceType, avoidanceBeforeDR[, class])

                avoidanceType:  "DODGE", "PARRY", "MELEE_HIT_AVOID"
                avoidanceBeforeDR: let's use 0, since that's what http://www.wowace.com/addons/libstatlogic-1-2/tickets/16-division-by-zero-on-ptr-4-3/ is experiencing
                class: was "6" a guy said
            --]]
            local n;

            n = StatLogic:GetAvoidanceAfterDR("DODGE", 0, 6);
            n = StatLogic:GetAvoidanceAfterDR("PARRY", 0, 6);
    end;

This should hopefully be fixed in r81.

This is on the MoP beta, using r86 of LibStaticLogic. Caught by BugSack.

@myrroddin This bug in r86 should be fixed in r87. It's a different bug (i.e. in a different spot).

• Resilience no longer affects critical strikes against you,
  and i added a dummy combat rating value for "PVP Power" so it wouldn't divide by zero.

• For anything else, the extra checks i added should help pinpoint the problem (by telling me combat rating and class that the calculation is being performed for)
