Period.
Programming schmogamming. The actual code might vary but the results being output are identical despite hardware differences.

40:60. And if I remember my fact sheet, that changes over 100 mph to more like 20:80 for improved stability.

And it works pretty fine.
You aren’t saving hardly any power by adjusting the bias to 0:100, you are still powering all the extra rotating mass... just using the ground to do it indirectly instead of the driveshaft.

I could see this being useful for burnout contests and Dyno pulls. And that’s about it.
I thought I’d hate the awd, but it’s pretty good.
I think the old viscous coupling was a bit smoother to engage. I’m sure with a less laggy turbo you could take advantage to really power thru the corners by applying power early and tightening the corner to let the car 4 wheel drift slightly under power on the way out. That’s how we did it on the “good old days” of viscous couplings and torsens
Don't forget turn in and steering feel.

There's a considerable difference when I went xDelete.
