>You're counting every second of every image that a child sees as a separate "image" that is learned. I'm counting the number of objects that a child sees, because people aren't doing frame-capture and analysis on every image, they're doing lazy interpolation (which is why all your peripheral vision in in monochrome but you perceive it as full color).

Then it sounds like he is slightly overestimating the dataset (since some of the frame is monochrome) and you are massively underestimating it.
