On page 51 of CO, it covers the rules for procuring equipment and personnel during the campaign. In paragraph two, it covers the shipping times. This formula seems off to me:
[7 - (1d6 + availability)] / 4 = # of months (min 1 month).
So by this formula a Heavy Battlemech takes on average -0.625 months:
[7 - (3.5 + 6)] / 4 = [7 - 9.5] / 4 = -2.5 / 4 = -0.625 months.
That has got to be an error. My searches have resulted in no hits on this topic so I posted in order to get an answer.
I'm thinking it was meant to be [7 + (1d6 + A)] / 4 and thus a Hvy Mech takes 4.125 months
or
it was meant to be [(1D6 + A) - 7] / 4 and thus 0.625 months.
Non-the-less, its strange.
