Formula

$$aP = \frac{\sum_{i=1}^{n} (P_i \times V_i)}{\sum_{i=1}^{n} V_i} = \frac{(P_1 \times V_1) + \dots + (P_n \times V_n)}{V_1 + \dots + V_n}$$

$aP$: Weighted average gravity in °P

$P_i$: Gravity of turn $i$ in °P

$V_i$: Volume of turn $i$ in bbls

$n$: Total number of complete turns (1 to 4)
