Granted this is off memory, using 4 blocks is unoptimal. 9 charcoal, 18 branches, or 3 blocks w/ 3 branches will fill up a crucible for 12 hours. 1 tick is 40 minutes. The calculations you did rounded up terribly bad. 1 block lasts for 3 hours and 20 minutes, not 3 hours.
Charcoal: 9 for 12 hours, 42 for a full cycle.
Branches: 18 for 12 hours, 84 for a full cycle.
Blocks: 3.6 for 12 hours, 16.8 for a full cycle.
