1000 ignitions? That was our intern hazing ritual. Typically took about
four hours.

I second that with >1000 successful torch ignitions under my belt.
Years ago I turned down a job with Beal Aerospace because he wouldn't
budge from HTP as his main/only oxidizer.
When I suggested he think about alternative oxidizers like LOx, he nearly
got angry. With such a closed mind attitude I felt the company's days were
numbered.
The rest is history.

oxidizer uses RGHP and the fuel is NOT petroleum-based (e.g. RP1,
Kerosene, etc.).
I take it RGHP is "rocket grade hydrogen peroxide"?
To me, the main market for hypergolics seems like it's orbital
maneuvering. Brief pulses of thrust which have to be precise are a
scenario where self-ignition can be a big plus, and since less fuel is
involved, fuel cost is less of an issue. For most uses, though, torch
igniters seem quite satisfactory.
