Hey, guys, what's the problem? This is the greatest improvement since the sliced bread. Far better than muck about those registers and better than the "classic" solution from the Owner's Handbook. 6 steps only.

OK, I have a big face, but I'm groved up here (MoHPC), and I can remember the discussions at the 2000's. And yes, I'm not really clever, just googled the simple linear regression on Wikipedia - but really missing those clever discussions like 15 years before...

BTW: the result is 11.09933164 and 0.1593408619. I don't know it is good for you or not...

PS.: and yes, I know you're will reflect only my words, not my 6 steps solution... That is exactly what I want to say...
