User blog:XXKeo/Expeditions 21 and 5, to 37 and 38

Calculated with the losses, the hourly rate you'd get resources. *Losses are calculated assuming that you're using only the common submarines, mutsuki class and tenryuu class kai.

241 / 198 / 13 / 13 for both expeditions 5 and 21

92 / 83 / 167 / 0 with expeditions 37 and 38

If actively sending out expeditions, it's best to send out 5 and 21 if you'd like the most fuel and ammo gain.
