Need help with deciphering the DXO profile view?

Specially so I was wondering about the Tamron SP 10-24MM F/3.5-4.5 Di II LD. The vertical and horizontal lines diverge dramatically. Would that explain the heavy amount of chromatic aberration? Will this obvious divergence affect the overall sharpness across the image in a noticeable way? At some points the lines go up as well as down. Is this a sign of field curvature and will this create inconsistent image sharpness?

And what is up with 15 F4? Performance absolutely plummets. How can 10 3.5 perform much better? What could explain this behavior? Performance is abysmal.

Fairly often you can get higher vertical resolution at F8 but the horizontal resolution becomes a lot more inconsistent at f8 compared to F5.6. Which one is preferable? Higher resolution or less field curvature?

Field curvature?
