The spray pattern remains the same nomatter what the pressure. The volume of fuel changes.
The fuel head piston moves farther up the chamber as control pressure rises and allows more fuel to flow. An x-ray style diagram would help you see how that works.
BL likely set your WUR in the middle of spec for your application and region, I am simply suggesting you verify those numbers before moving on.
In order to take full advantage of the Leask modifications you need the pressure gage and an LM-1 or similar device reading A/F ratios that will allow you to fine tune the WUR to your specific application. You can rough tune using only the pressure gage but fine tuning must be done with an LM-1 or similar device.
If you need more info past what BL included with your WUR there are many threads on the subject.
