"Center weighted" and "targeted"
You basic announcement about the Color Parrot says:
"The White Reference Target is center-weighted to provide a more targeted reading."
Could you please tell us:
1. What "center weighted" means in this context ?
2. What "more targeted reading" means, and how the White Reference Target being center-weighted brings that about?
3. What is the significance of that to the performance of the Color Parrot?
