I finally got to watch them.
Nice!
While we have to miss out on seeing your pretty boy good looks, I like the format that you're using and would only suggest that you use more video, charts, pp cuts. For example, for Cigar's Pacific Classic, the screen shot was a great place to start - introduce the horses, show their relative positioning, odds, say a little about them etc., but I think you could have enchanced the lesson there by including some actual race clip and perhaps some of the chart or a cut of the horses's pps. Evidence always makes for a more lasting impression, you used that tool very well in the Rapid Redux race.
That said -- if you just conquer the sound so we can hear you, you've already produced something that is better than what the tracks or racing programs are putting out.
