I have recollections of some people here mentioning that pintle injectors
offered deeper throttling capability (with a given finite development budget)?
That’s probably going back to discussions from the early Masten startup days?

May have answered the question after jogging my aging memory:
In the late 90's at EMRTC New Mexico Tech I conducted firings for TRW with a
pindle at the 40K level with Tom as the project engineer and Maurice O Brian
test tech. Then in 2003 from my home in the Mojave desert I did loan Tom my 75K
LOx/Kero injector as a demonstrator for 6 month. Guess It stuck.

They use a pintle injector because when they designed it that was far cheaper
than a flat plate.
