OK Jon,Here's the friendly advice. You are working hard to convince us something, yet you are not gaining any traction, so far as I can see, with anyone. In trying to sell us economy, you are extremely inefficient. You use the same techniques that you have for more than a decade at letsrun, and yet, from the beginning, you mostly provoke others to question many things about you, including your ability to grasp, interpret, and convey, the science you read, and occasionally why you weren't a better runner, or trained some leading runner yourself, if you were so smart. You are no doubt a great runner for your age, and better than many at any age. At the risk of lumping you with coaches that have achieved greatness, you now accuse Daniels, and you have accused Lydiard and Canova, of misunderstanding the science. You must concede that it is possible to achieve great performances, yet possess grave misunderstandings of how you achieved it.I cannot speak for others, but considering myself more like a scientist, here are some reasons I hesitate to accept your unique concepts that deviate from my own notions of basic physiology:- Where is your data? I see many conclusions, but very little data. The data you do present, representing "basic physiology" seems to always support, or reaffirm, rather than contradict, any conventional notions I had before. I have struggled for a decade to see your "aerobic dogma" as dogma, or factors that improve economy exclusively contradicting (rather than complementing) aerobic factors determining performance improvement. Jack Daniels published material based on real VO2 and speed measurements of a rather large population, including elite runners, and formed relations from the real measurements. You come up with an imaginary scenario, coupled with some assumptions, backed up by your personal assurance and re-assurance that it is realistic. Your scenario contradicts some of Daniels' statements derived from real data, and you presume that Daniels must have learned so much since then, and would agree with you today. I would be tempted to consider your claims further if you actually presented us with some real contradictory data, rather than fabricating scenarios with twins assuming the same absolute VO2max. You've effectively contradicted Daniels' real data, with your imagination, and you hope by now he has since come around to his senses.- Should Daniels recant his 1979 statements? I guess Daniels rightly stands by the VO2 measurements and the velocity measurements, and Gilbert stands by the math that generated a good curve-fit of VO2 to velocity. This data is still as real and the math still as applicable in 2016 as much as it was in 1979. What can change is the interpretation and implication of the data, in a larger exercise context, and perhaps the importance of the role of other non-oxygen factors which were lost as confounding noise during the curve-fitting exercise of VO2 to velocity. Maybe Daniels has other papers that explore economy further -- some of the "brilliant research" that you acknowledge that he has done. Maybe you could point us to a few of those, as part of your arguments supporting the points you want us to accept.- Who is presumptuous? I presume the point of a published work "Oxygen Power" was to show the role of "oxygen" in generating sustained "power". Economy briefly appears as something that reduces the correlation of the curve-fit of VO2 to velocity, influencing some comparable fit measure of "r" smaller than 1. While Daniels makes no secret that economy can vary widely between runners with the same VO2max measurements, the focus of "Oxygen Power" was the relation of Oxygen, and Power. Economy should be featured in a complementary paper "Non-oxygen Power" or "Economic Powers" -- maybe you would like to write this one, or find someone who wrote it, or will write it?- How do you respond to doubt? Despite me asking you 4 or 5 times, you have still not shown us where your 3 hour runner, fits in the Table 1 of your linked Economy paper. This helps illustrate whether we are struggling to meet the lowest bar of determining the mere existence of such a runner, or rather whether such an uneconomic runner is more the norm, numbering in the millions. Using your 85% figure, that you obtained from the same paper, your paper shows this athlete does not possess "representative VO2 values for different caliber of runners from the existing literature". I already know the answer, because I did read your paper, but can't help feel that you should do more of your own work when answering doubts. You actually have the data, and you have a choice. You chose not to use the data. You presented us with an economy paper with data showing us "representative VO2 values … from the existing literature", yet when questioned about the existence of such an uneconomic runner, you chose to personally reassure us that such a runner exists, and you chose to question my own links to reality. Maybe you really are "too lazy". If you want me (I don't speak for anyone else) to appreciate you as a scientist, you must make a scientific choice when responding to real doubt.- What is your imaginary scenario supposed to show us? I guess if someone has a measured 68 VO2max, and 20% bodyfat, and a 3-hour marathon time, they can make big improvements if I train, lose weight and improve technique. This is hardly a remarkable statement, and at best it is applicable to a small subset of the running population. There is no doubt that a measured VO2max of 68 indicates a huge potential for the 3 hour runner. Looking up a 3 hour marathon in a VDOT table could be a huge source of encouragement, by highlighting that economy is lacking. The doubt is how many there are that possess such a poor economy, and if this can be applied to runners who have elite performances. What about the other twin? Can your 2 hour twin further improve his economy? Can he improve his engine with PEDs? These doubts remain unaddressed, despite your conclusions to the contrary.- Are the conclusions from this illustrative imaginary scenario something exceptional, or something that we can generalize to a whole population? You already told me it was NOT something we could generalize (even asking where would I get such an idea?). How does this extreme example fit in a thread which seems to want to say that PEDs are not necessary for anyone and everyone, in order to be the "best that they can be". If this is NOT something we can generalize, how do you get from your imaginary scenario, to "my point still stands: ELITE RUNNERS USE LESS OXYGEN, GLYCOGEN AND FATS TO RACE FASTER." (Glycogen and fats? Yikes! More conclusions with missing data!).- What is the message from your scenario? I gather that it is something like, any of the millions of uneconomic athletes with a measured VO2max of 68, and a 3-hour marathon PB, could become the next Derek Clayton (measured VO2max of 69, marathon PB 2:08:33) without PEDs, just by training, losing weight and improving technique. And more generally, any athlete, regardless of their measured VO2max, can always improve economy factors, and therefore performance, rendering PEDs superfluous, or even worse, ineffective, as they don't target economy. It's a positive and hopeful message, but judging by the near universal reactions spanning more than a decade, you seem to be the wrong messenger. The first challenge you face is, "OK, but what if we increase the size of the engine, and economy"? You can personally reassure us again that this is a "false concept" contradicting basic physiology, or show us the science. The choice is yours.
