Do these two equations line up? The result I'm getting is nowhere near close, so I'm not so sure...

Compare this image to the below equation: OtherStatCalcGen34.png

stat = round(((((iv + (2 * base) + (ev/4)) * level)/100) + 5),1) * Nature("stat")

I'm not sure, but is this what you want?

No luck yet, but I'll crunch the numbers...

There's no absolute value (or rounding) in the image.

What I got from the image:

Other stat = ((((IV + 2 * Base + EV / 4) * Level) / 100) + 5) * Nature
