Minotaur XP BV listed at 294, I'm getting 276.
Calculated by hand.
Defensive BV
2.5 x 45 (total armor) = 112.5
1.5 x 21 (total IS) = 31.5
(31.5 + 112.5) x (1.2 + 0.1) = 187.2
TOTAL: 187.2
Offensive BV
19 + 19 (2 iHSLs) + 47 (SRM-5) + 3.6 (600 kg of ammo ÷ 1000, x 6) = 88.6
88.6 x 1.00 (speed factor) = 88.6
TOTAL: 88.6
187.2 (defensive BV) + 88.6 (offensive BV) = 275.8, round up to 276
