Sky commisioned the report, but Sheffield Uni are publishing it when they have studied the data. What's so complicated to understand? That's how it often works in Academia - a company goes to a University, commissions a study to gather data on something that hasn't been studied before and uses the data, then the University release their report when they have studied the data.
Sky needed the initial report on the data for Henao's physiological profile in 2014, they don't need the final report of the University's findings. That's how I understand it anyway. i.e. it's up to Sheffield Uni to study the data to compile a report. That could take several years, we don't know what the timescale or priority to complete their findings is. A couple of years I would say at least.
“The research around this case has been taken very seriously and we undertook a large amount of complex scientific analysis before giving our recommendation for Sergio to be allowed to return to racing,” he stated on Wednesday.
“It’s still our intention to publish the results in the scientific literature. There are many processes to take into account when you write and publish scientific papers and delays of over a year are not unusual in these cases. We hope it can be done as soon as possible.”
What likely happened, and I'm not defending Sky by any means, is they commissioned a report by a researcher who works at a University I believe.
Professors/researchers really make their name/money and pay increases from getting published in peer review journals.
Thus, the agreement may have been that Sky will not release, had a non-disclosure agreement with the author, who wants to try and get published by a peer-review respected journal, before any info is publicly released.
The author probably just wants to protect himself...the byproduct, Sky is protected, for at least awhile, until eventually the report will make its way out into the public realm.
This is the same scenario that Sky admitted, along with Froome, regarding his "Testing" earlier in the year. They weren't going to public release information on the study, some basic stuff only, and the author/researchers want to get it published in a peer review journal, then we will all see it for ourselves.
Surely a PR/Media annoucement would be done shortly before the publishing of the documents/research of these riders.
