The real question is, can a more accurate PM on the market make a weekend athlete any better than a less accurate PM. I'm referring to weekend athletes, the people in this discussion. I doubt it. To this end, the discussion and dissection of PM... probably doesn't mean much for weekenders than say a pro pursuit cyclists. They should really stop pushing weekenders into buying PMs and into thinking that PMs will somehow enable them to do something that requires genetic blessing. No PM is gonna overcome a genetic deficit.
