It's quite clear now that (with one occasional exception) the session ends at the end of the first 90 knockout period. With five cars supposedly being knocked out after, that effectively shortens the session by nine minutes. There's your problem.
The 'occasional exception' is if a car in the top three or four potential knockout victims needs to go again and they make the decision to do so straight after the first knockout.
Most of the teams did a much better job today and the result was an even worse qually than Aus.
