I never said it made any sense. It makes perfect sense that 47 minutes training would get better training than 20 minutes. But I've got to ask you, if there is no assigned value to either 47 minutes or 20 minutes, then how does one get a higher value than the other?
What you're saying, and you could be correct I'm not debating that at all, is that there is actually an assigned value to 47 minutes and 20 minutes? I think there would have to be assigned values to each number if one is guaranteed to get more training than the other.
What is the exact meaning to the word exponential?
