Lecture 3 excel exercise loss greater than Jeremy's loss

Hi guys, I’m in Lesson 3 of the part 1 course. I’m not able to achieve 0.08 loss like in the video, In fact my NN performs like a linear regression (going by the loss). Is it become of my random parameters I’ve chosen which leads to this difference?

Another doubt I had was using 2 sets of parameters means there are two Neural Networks in this case?

If you look carefully in the video, there’s a mistake where his loss function is calculated using rows 662-715 instead of 4-715. I got the same result when I changed it to that, after questioning my sanity for a while.
