I was just about to get out the popcorn as this was getting good.

Ah, Fred, I'll have to commend you on your selection of bait. You got me hook-line-and-sinker.
Im not quite a newbie to rocketry. Im not terribly active on this forum, but I am active on other forums more geared to experimental rocketry. Ive been a TRA member for 20 years (TRA #6012) and have been flying and building motors for years prior to that. Over the years Ive designed, constructed and either flown or tested over 1000 motors (mostly solid) using about 6-10 different oxidizers. Ive also built and constructed over 50 hybrids (in fact, its probably over 100) and participated in liquid projects. Ive built many solids (including sizable ones) from both homebrew AP and homebrew polymer binder and Ive achieved making a propellant with a zero exponent in doing so photo of such in flight

Over the decades, Ive developed many many spreadsheets and software applications relating to rocketry, like detailed tools for high quality AP manufacture, solid motor simulators, general rocket motor performance simulators, chemistry tools and other stuff. Some of this stuff has been publicly available for free download for literally decades. Some of it has been utilized by various universities all over the world as tools to assist their propulsion work. For example:

Ive spent thousands of hours (Yes literally!) on rocket equations over the past 20+ years. Mostly geared around propulsion but Ive also had a special interest for nozzle behaviour and the interaction with the aft end of a rocket with the surroundings. I derived and programmed every equation and line of code in my GrainsCAD application some 50,000 lines of code with thousands of complex geometric equations. Theres none of that 3rd party module stuff it was all done by me (other than the DirectX libraries). I produced all the geometric equations for my other solid propellant simulators including the equations to simulate the more complex grain geometries. Greg Deputy asked to use these for his BurnsSim software which I happily agreed for no cost. It took me hundreds of head throbbing hours to produce and verify these incredibly complex equations.

Ive manufactured the parts for an electrically driven liquid propellant turbo pump

I fly all my rockets from parts that I make and design myself including electronics, nose cones, body tubes, parachutes, pyroless deployment devices, pyroless release (detachment) devices, motor casings, combustion chambers, nozzles, liners, propellant, sometimes oxidizer and fuel, tanks, injectors, check valves, remote hose disconnect devices, pistons, couplers, boattails, fins etc.
I was involved in the 1:1 scale V2 project where I had the challenging job of developing the separation system had to be pyroless, had to ensure a 450Kg rocket separated and deployed that was simulated to reach an apogee of a few hundred feet (!), it was a challenge and we pulled it off. This included designing and constructing remote hose disconnects that provided the safe filling of the deployment devices.

As Ive previously mentioned here, Ive also designed and constructed my HPR pyroless deployment device which Ive been solely relying on since 2010

Probably the 1st person in Tripoli to make and use composite wound phenolic nozzles (nearly 20 years ago). Probably the 1st person to make both oxidizer and fuel and flew such on sizeable motors. Supplied numerous large (up to O designation) experimental motors for large projects. Produced hybrids with >18sec burn time.
