yield Yield Question

For my first year with exotics I'm growing 2 Bhuts, 1 Scorp and 1 7 Pod. They are all getting the same sun, same feed same everything. the 2 Bhuts combined have close to 100 small pods and or flowers (still early). The next best is the Scorpian with about 30 pods / flowers and the 7 Pod a distant 3rd with about 15 pods / flowers.

Is this normal yield for each of these strains.
