Is there a way to look at the race details? At least the lap times? The main thing I'm trying to better understand is how the different tires "fall off". If I could look at the lap times I could see, "1:30, 1:30.1, 1:30.2" and could see that tire x seems to be dropping off about 1 tenth per lap. It's pretty hard to do any real strategy without this info.
On any race result click the "finishing time" for a driver and you will get their lap-by-lap data. Actual tyre wear and fuel usage data is available for your drivers, but you can also see lap times for rivals.
If you are checking yesterday's race results, that's just unlucky timing. Yesterday (only yesterday) we didn't report this data. It will be back for any races from today. If you look at older races in the season or your history they should have it too.
But this screen does not show if a boost was used on any particular lap, so lap times could be influenced by this and also DRS. Making it difficult to see the tyre drop off.
