Just want to comment on this after our first race weekend with it and say that this is by far the most fun and efficient qualifying system that we've had in FSR since I joined.
It keeps up pressure knowing you only have 4 goes, but it felt like we had more time than before, so you didn't have to force yourself to get a lap started before the guys on hotlaps caught you. I was able to bide my time and look for gaps etc.
Also, it takes even less time in total than before, if you account for the break we normally had between Q1 and Q2.
With regards to the tyre rule, I will side with Kuba on this one as a grid with mixed tyre strategies from pole all the way through will make for one helluva race I believe - I am not even sure why the rule exists in real (*insert copyrighted open wheeler racing here*), as it's basically a penalty for being better than the guys from 11 downwards. If the TOA could reconsider it one day, it would be great.
But it's by no means a deal breaker, and the huge improvement in the format alone is more than enough already.
