Indeed. 10 builds per minute, 24hrs a day. But not as impressive as
the scale of the development team able to create enough changes to
trigger so many builds and the scale of the test infrastructure able
to consume them!

Assume one developer makes 10 changes a day and each change gets built
for 10 different targets... 100,000 builds per week implies a team of
over 140 developers.
