My initial inclination was to dial in -0.3, but on 80% of those images I find that adjustment slightly underexposes the image. The camera is remarkably good - and better than earlier models - in correctly metering the scene.
I find the histogram is not precise for small blown highlights that can be extremely hard to recover. I often use a combination of the histogram and blinking highlights. And there is an art to metering as lighting conditions can easily change in a few seconds if little more than a wispy cloud covers the sun. You need to understand how changes in light affect your chosen exposure mode and the meter.
Matrix metering is much more than simply spot metering. It takes into consideration the entire scene and references the scene against a range of similar scenes to determine exposure. It is remarkably good - but still may need adjustment. For wildlife, center weighted tends to work better. And for some subjects (moon, white birds, snow), an old rule of thumb with spot metering and manual exposure may work better.
