I mean, isn’t that what racing is about—pushing yourself to excel? Competing. Be it against your own times, the clock, or your buddy Steve, racing implies competition. If the time comes when you can no longer beat the guy next to you, well, then the time has come when you can no longer beat him. No chart is going to get you to the finish line faster.
It was nice to see Running Times editor Jonathan Beverly revisit an issue he thought he would be all for when he became a Master. Now that he is actually a Master he is not in favor of the idea (to paraphrase, of course). In six plus years, when I become a Master, perhaps I will change my mind as well and be all in for these wonky math charts which help me run faster than I ever actually had. But, I doubt it.
