Default to milliseconds internally. The behavior would be incorrect with any other time unit anyway: due to multiple unit.toMillis(unit.toMillis(unit.toMillis(x))) conversions. Extract duplicating code in unit test.
NakadiException.throwNonNull throws IllegalStateException while NakadiException is itself exception, also throwNonNull is a non null check that is retrofitted to throw unconditionally. This all is rather confusing.

Extracted for testing.

This still looks like too aggressive increase. workingInterval = startingInterval * pow(workingInterval, 2) would be OK (and easier to review).

Would previously fail here as accumulated time was 202 milliseconds (instead of 101).
