The idea behind your claim is reasonably strong, but your numbers are so imaginary that they actually harm this discussion. There are no universal "rules for learning" like this. If there were, education research would have been wrapped up a long time ago.

Learning is an incredibly complex combination of content, medium, background, strategy, mental state, mental ability, and more, and it varies widely based on subject material. There appear to be some advantages for certain teaching strategies under certain conditions for particular populations, but there is very little research that clearly establishes a more generalizable trend.
