Quoting again the doc:
"Operations include tank tests, pre-flight operations, suborbital launches, and orbital launches. SpaceX is
still in the testing stages of the launch vehicle, including ongoing Starship prototype tests that have been
approved under a separate license. SpaceX also will need to conduct similar tests of Super Heavy
prototypes, which have not yet been approved under a separate license. In the early stages of the
Starship/Super Heavy program, SpaceX would conduct more tests (tank tests, static fire engine tests, and
suborbital launches) and fewer orbital launches annually. If SpaceX becomes more successful with tests,
the program would shift to more orbital launches and fewer tests."
And the section the previous extract came from:
"SpaceX is still determining the number of prototypes that it will build and test. SpaceX is proposing to
conduct approximately 10 tank tests a month. SpaceX estimates a 10 percent rate of anomalies during
tank testing. An anomaly would result in an explosion and the spread of debris. The distance for which
debris could spread is considered the blast danger area; SpaceX would determine this area prior to the
test. The blast danger area for tank tests would be within the hard checkpoint area (Figure 2-4). Given
the rates above, SpaceX estimates that one tank test each month may result in an anomaly and
potentially an explosion."
