Review comment:
nit: extract `1_000_000` and `1000` to be a constant with meaningful
name or use predefined ones in java library.

Review comment:
Seems the same logic (`if (condition) {return...} return ...`) appears
multiple times, can it be included inside a method, e.g. just embed it in the
method defined in `ProjectionUtil`?
