There other factors besides rx count that go into the Sh*tshow Determination Matrix. We had stores that only did 100 per day but the RPH was alone with no cashiers. Imagine ringing up 100 scripts and filling 100. Of course a low vol store has no inventory so a high percentage of rx's need a jobber to complete. That in itself can be quite a task dealing with all the partial fills, manufacturer changes , and completions.
The quality of the clientele matters. A midwestern crowd probably just picks up the scripts with no question, no fuss. On the other hand certain tribe members can make every interaction into high drama.
For the OP, no matter what, make sure your safety tether isn't frayed. Starting out as a retail RPH w/ no more training wheels will seem like this.
