Thank you very much @andrehche! Are you good with my suggested rewrite of the first paragraph? If so, I'll commit that change and approve the PR.

The section on Multiple circuits in the same job is incorrect. If you submit a large job, it may get divided into smaller jobs and thus interleave with cal jobs. We can fix it in this PR or a separate one.

Also we can probably remove the cal time on smaller device (5-7 qubits). It's been a long time since we've had devices that small (on production) 😁.

Also it sounds like we don't do daily cal anymore. So this section should also be updated:

How long do calibration jobs run for? We run both daily and hourly calibration jobs. Daily calibrations on a smaller device (5-7 qubits) may take about 30 minutes, while for larger devices (7+ qubits) they could take about 90 minutes. The hourly calibrations run for about 2-3 minutes each hour.

@jyu00 Thanks for the catch. I'll update that too.

Hi @andrehche - This is looking good! Is there any way I can help get it finished up so it can be merged?

beckykd thanks for the nudge -- still waiting on some internal feedback on this version, so I think we will have some revisions, will update here.
