Sharing my Demo Video Stats - Any tips or comparisons?

Well I had a moment of astonishment today when I looked at our page analytics for the set of 9 demo videos our company serves up for prospects.

I was surprised that the videos actually had great stats according to GA. I expected the average time on page to be much lower than the video time suggesting that users bug out before the video finished. Looking at the past year the average time on page was the same or more than the video length.

Are our prospects actually watching these things in their entirety? Wow, especially since they are very instructional and plain but maybe that is what our prospects want to see for our industry.

Does anyone place a lot of emphasis on demo videos and their stats? Any comparisons?
