Some interesting posts here among the troll posts. I would stress looking at the data above all else (the he said, she said). We are looking for a marked increase in performance. Look at the two athletes on the front page just declared null and void.
Ivan Tsikhan - marked improvement from 2003 onwards (5m+) in the Hammer, aged 26, from already an elite level (79m - his peak at age 24). Likely doped from 2003 onwards, only scaling back in 2006, when nothing major was on to aim for.
Nadzheya Ostapchuk - Applying the same information (Belarus dictatorship, 2003) here shows Ostapchuk gained 1m in the 2003 off-season, breaking 20m in 2003 and 21m in 2005. Only in 2009 did she not break 20m (an off year? Surprising given how many records were set in 2009.. context needed here), although the most major outlier is 21.5m in the 2012 OG (probably an attempt to beat Adams, but it looked totally ridiculous). That's obvious, but the rest is probably from a bit less usage than Tsikhan, however it's fair to say that she gained at least 1m and likely 1.5m from doping. Also, she doesn't pass the 'look test' (although this test is dubious at best).
Lilya Shobukhova - Same as Tsikhan, improves at age 26 (2003) to get a new higher peak, then went totally gung-ho from 2008 (14:23 5000m) onwards as she aimed at Beijing/emerging Marathon money. I'm pleased that the blood passport has worked and her hardest doping period at least has been wiped out, and she probably won't return aged 37 (then I remember that Russian running super-elite times vs. Kelly Holmes on the wrong side of 40..).
This couldn't be applied in the first example above. Valerie Adams' achievements really stand out when we take this into account - she's been the best in the world now for at least 10 years in the Shot Put, ultra consistent and eventually peaking above 21m. A clean WR holder?
For Paula, you should use her 2:17 record, if the 2:15 was drafted behind Wejo (I should re-watch the footage! I likely saw it as a kid). How does that stack up with her track performances? Her consistency (over 15+ years) marks her out as clean, along with being a 'total slow-twitch machine'. She'd have so many track medals if she could produce any kick (or not be beaten by dopers to medals and WRs on the track, not including the East Africans here).
Also, why is there such a spate of doping from 2003 onwards? I thought that was a clean year, what with Collins winning the 100m... or was the focus on Sprinting meaning that the Endurance cheats took on some new technology?
