Welcome to nerddom.
I'll see how your results compare to my spreadsheet that I created when I was bored.
I also calculated the lead in body lengths. You know shoot 1 goose length or 2 goose lengths ahead. That might be good to add. Leading a goose or a wood duck at the same distance and speed is the same in feet, but a lot difference relative to their size.
I did surface plots for distance versus speed for straight crossing shots.
I forget how I did the deceleration. I had some data from a link and I think I did a curve fit.
Anybody have any data on the impact of wind speed.
A mallard crossing at 40 yards with a ground speed of 30 mph and a 10 mph tail wind is going to be different than with a 10 mph head wind, but I have no clue how much.
We had mallards coming in crossing to a 25 mph head wind and most wanted to land at about 40 and we shot like crap. I really think we weren't account for the wind. The birds just looked like they were going very slow and almost hanging, but the wind was pushing the shot behind them. I got at least my 4 plus a black but it took an embarrassing number of shells and the three of us only ended with 9 ducks and a huge number of empties.

I don't know the science, but initially, the pellets are all interacting and none are flying through clean area and most are in the draft of the pellets in front of them. They quickly spread out and probably are in clean air for most of the flight. Given that they are symmetric, they would still fly on average straight. Interesting question on how far from straight would they vary if they were in the worst possible orientation. If they rotate, would that negate this effect? They may be pro science, but not the simple single pellet ballistics. Steel shot does not fly like a knuckleball or does it? Throw a knuckleball too fast and it's called a homerun. Throw it just right and it's a real bitch to even catch. Don't forget the black cloud wad is supposed to hold the shot together longer. To say the reality of the physics is complicated is a huge understatement.
BTW, I'd be a bit skeptical of a chemistry teachers thoughts on aerodynamics. It's like taking advice from a nuclear engineer on it.
