you mean that "based on" designs for season 10 are shown as "brand new" or that the ratings of those parts are very very bad or that it is not exactly clear what they base on in sense of research or .. something else?
and, no idea - I have an aproach which might or might not work, but I can tell you in week 1 or week 2 of season 10
I made a 'new' exhaust when my research level showed as 'excellent or superb' yet still had 3 weeks 'research' to go.
I figured if it said superb, it must be the early rated superb research. It then got produced; and the display now states research level was 'okay' when it was made.
I know this is not correct; at least not to what I saw on screen.
So to me, this is a display bug regarding what current research is showing.
I also have other items that say it is currently 'superb' research level; but have all needed 2+ weeks left on superb before completing.
I am pretty sure that they are not going to be based on. I tested this with my steering, it took the current researchlevel for S10 and I did test bed, the current stat of power steering was total crap.
I am strictly against another season of instant parts. Everyone had the ability to test if that feature works (test bed). I tested it and even stated in the chat that its not working.
I also had to change my approach for next season, I started pretty late because I was fighting for div 2 victory and I still got my car in time. Its all done, still more than 2 days to start testing.
All dev for next season should be easily done, especially for bigger teams. Smaller teams and new teams could be screwed by that though, because they dont have the resources to create parts to simply test stuff.
