I've been myself also confused about the timeline issue because the dates of the "great change" range from 1989 to 1995 depending on who is describing the issue and if I am not mistaken, Frankie Andreu mentioned somewhere 1996 as the "watershed" year.
While my M.O. isn't to flood the forums with links into my blog to get more traffic, I wrote an entry on the "great change"-issue of cycling roughly a year ago and it is decently readable via the new algorithm of the Google Translate, if anyone is interested:

When I forwarded the timeline problem to the Dutch researcher Jules Heuberger, he also found the timelines totally inconsisted and gave a comment on the issue. As most CN-readers know, he is part of the emerging Dutch research tradition that takes a more skeptical approach about the efficacy of rHuEPO and he coauthored the famous Mont Ventoux - research allegedly showing no benefit with the hormone on the road.
If you don't mind me putting it like this, but you appear to be confusing multiple issues. There are three key strands: 1) When did EPO arrive?; 2) Were there step-changes in performance by which we can date 'epochs' of Gen-EPO?; 3) Can such step-changes really be credited to EPO, or is its role as a performance enhancer just a myth?
Let's take the first one. It's fairly well established at this stage that by the late eighties - 1988 specifically - people knew EPO was arriving and believed it had the power to replace blood transfusions. We have newspaper reports from around the time of the Calgary Games talking of its future potential, we have Les Earnest, we have the evidence you cite, such as Winnen.
But who was using it? We know that some in the pharma industry wanted it to be used in sports. Søren Kragbak is one who has spoken of this. Were some sports people being used as human guinea pigs, supplied with the drug free or at a deep discount? This can't be ruled out.
When did EPO become a cheap alternative to blood transfusions? We both know that one of the drawbacks of blood bags at that time was expense and we both know that EPO is said to have made economic sense. But at CHF 800 - what's that, circa fifteen hundred euro today, so in real money quite a chunk of change in the early 1990s - how many could actually afford such a drug?
Was cycling a single sport at that time, something happening in one corner would be repeated in others? Or did it have clear and distinct cultures? Evidence suggests that Italian cycling had a more science-based culture than, say, French cycling. And had more government support, producing the likes of Francesco Conconi. It is not difficult to see, within cycling, first an Italian nexus. And then to see Spanish cycling rising up and following Italy's example (with the likes of Eufemiano Fuentes and Sabino Padilla). Is it possible that the French culture took longer still to catch up, that Festina's decision in 1993 to 'get with the programme' is believable? That Postal's decision in 1995 is believable?
When did EPO become a team-wide phenomenon? It isn't likely its use would have been team-wide from the get-go. As with blood bags, it would seem likely that its use was limited to designated riders at designated races. But at some point the upward swing in cycling's economics - the money coming into the sport and the increased need for a performance-based return on that investment throughout the season and not just at one or two races - would have met the downward slide of EPO's price and team-wide doping made economic sense (such as the decision made by Festina in 1993).
If you take these different issues, the testimonies of different riders - while all being somewhat self-centered and blinkered - isn't as confusing as when presented by those who speak definitively of a Year One for Gen-EPO.
As for the other issues, the performance stuff, I don't see the relevance. EPO was real, the fear of EPO was real - both in the belief in the bodies piling up on mortuary slabs and in the belief that it was performance enhancing. EPO was clearly having an effect on the sport. Whether you believe it was or was not having an effect on the athlete, that is quite irrelevant to the issue of when, how and where EPO arrived.
