Aside from the off chance your 358 is sick, I'd still go back into its settings menus and check for any dialed in compensation and zero it. I'm not getting the point of your incident metering technique in either setting. Ratios??? Have you simply taken a single outdoor incident reading with the dome pointed at the camera, at, say, ISO 200, dialed in the setting manually on your dslr and checked the results?
