Ahh thank you so much! That's all so nice of you to say, and also thank you for referring to me by my completely legitimate title :)
And great question about the stats! So originally, these were a somewhat-silly side thing that I included as a little extra inspiration for people who wanted to make a pokemon out of themselves, but there's still thought put into them. They're largely fueled by the attribute scores (like "helpful", "good vibes" etc) but with a few extra bonuses derived from the certain answers to specific questions. They're not actually calculated as a number, but rather as a percentage, so that everyone who takes this test gets a stat total of 450, give or take 10 pts from rounding shenanigans. I picked that number because it's the stat total of Piloswine, which could either be considered a final evolution or a middle evolution, depending on what game it's in. Potential room for growth, or potential final form, depending on how you want to look at it, but definitely not a baby!
As for the reasoning behind specifc stats, there are some attributes that are obvious (e.g. a high "defensive" score would add more defense, obvs) but there's some that are more associational. So for instance, your "helpful" and "good vibes" attributes are shared by high-HP pokemon (think Chansey, Wailord, Alomomola, Lapras, etc) and that surely contributed to your crazy high HP stat.
I hope that answers your question and was also not too boring :)
