Can I have a complex schedule that runs the same flow at the same time with different parameters?

You can check <https://docs.prefect.io/core/concepts/schedules.html#clocks|this>

Cool - they will run concurrently with this schedule?

With an agent yep, just dont do more than 10 concurrent runs. That is the limit (of the scheduler)

Just to confirm, you mean no more than 10 concurrent schedules for 1 flow, or is there a 10 concurrent run limit globally?

So the scheduler runs every 1.5 or 2 mins and scheduled the next 10 flows so if you have 13 concurrent, 3 will get lost

In other words, I can have `n` other flows that run at say 7pm EST, and this other flow that kicks off 10 runs at 7pm with no issue

Yes exactly the 10 future flow runs schedules is on a per flow basis
