The actual model that more closely resembles what we need should have the bare minimum of E2E tests, quite a number of service tests and the vast majority should be unit tests.

Exponential model: x = 10^hy

So if the height h goes from 1 to 2 to 3 then we have 1 E2E test to 100 service tests to 10,000 unit tests.

There is a physical object which has these properties, it is called an exponential horn.
