Naboo, nice ducks on the link mate
And they are a very good example of when to use incident light metering, as those reflections on the water, or no reflections as the case may be when the duck moves, will throw out a normal reflected light meter reading a lot.
You've also discovered a disadvantage of the palm method, in that its accuracy depends on the light falling on your palm being the same as the light falling on the subject. Most of the time, it is - but not always. And when it's not, you can often move to a position where it is for the purposes of metering, and then reposition your self, such as when you're shooting from under the shade of a tree. But if you're shooting a landscape across the valley in sunlight, but your side of the hill is in shade, then it's tricky
Technically, an incident light reading should measure the maximum brightness of the light falling on the subject, from the subject position back towards the camera. Which is why you might see a wedding photographer holding up their meter next to the couple, with its little white dome angled towards the sun. Or when setting the back-light in a studio portrait, the meter should be pointed at the back light head, from the subject position, and completely in the opposite direction from the camera.
Like most things it can get complicated but in practise it usually works well. I use the palm method a lot, even when I'm set on an auto exposure mode to cope better with changeable light levels. Providing I'm in the same light as the subject, then if I simply put my palm up to the camera, the meter reading will change by a stop and a bit. If I'm in Av and the shutter is reading 1/125sec, then when I put my palm up to the camera, the shutter speed should shift up to 1/250sec or 1/300sec. Maybe not always depending on the kind of effect I'm after, but usually if it doesn't do this, there's a good reason and I need to recheck everything. It's just a very quick and handy double check - quicker than scrutinising the histogram.

. Also, I couldn't find a way to get the rear display to show the duplicate display of the top control panel (as it can), with the shutter button held down, which meant that I couldn't read the EV meter with the camera hanging down lower, supported by the strap around my neck.
