Hello! We checked out out first day of on-demand build minutes and see an in-balance as to what is expected.

We had 58 builds of our app which take around 6m each:

And we got “charged” 10h of concurrent builds.

That kind of left us wondering.. 6 mins at 58 builds is only ~6 hours. Also not every push will encur on-demand for this project, since those 58 builds were comitted and pushed throughout the day and not at the same time. We had 50 cancelled builds, although it takes 5s to 30s to cancel. So even adding 50 builds at 30 seconds, that’s only an additional ~30 minutes.

That leaves us wondering, how are the on-demand concurrent builds calculated? We are perhaps missing something, although on paper it is not so obvious.

Happy to give team and project names as references, although perhaps the explanation is clear already.
