Parrot Cannon,
I'm amazed on how accurate your program is when validated with data from other sources.
That you have successfully built what many would call the holy grail and made it available to us for free, says a lot about yourself.
DD should award you a Kewpie.

Thank you for the kind feed back. I started making black powder for rockets in my early teens. I think this lead to my getting a degrees in chemistry and mathematics. I enjoy gathering and analyzing data. When I bought my first mortar from Dom about 5 years ago I started to analyze data and teach myself ballistics and after retirement have been able to develop sufficient understanding of the physics involved to create these programs. I would build cannons but I do not have the money or training to pursue this interest.
