This is my own personal preference, but often times I think an extreme spread collar can emphasize that it is too short. Noodles, your collar is perfectly within acceptable and even good for SF standards.
That said, I agree with Elio and prefer them to be taller, and in my case slightly less spread to emphasize the height. Again this is my personal opinion, as often I find even Clags' collars to be too short and too spread for my taste.
I agree. Less spread will make it not look apparent.
Noodles, you can shoot for this spread.
