The paper clearly said that the average time from a PR announcing TLD to publication of full results was 300 days.
It did not say 300 days from datalock.
BTW, it also says that failed trials usually take longer. The clock from data lock is now 335 and ticking.
Reality is vitualy all companies report TLD in a PR very soon after the data is available. So the paper did not even provide stats on companies that failed to PR the TLD.
