Solved

Practice session times are off by a second for same tire used

Why in practice session from one month the times of SS an S are wrong 
In one session differences of one second per turn and sometimes the s are faster than the SS

Yup I too observed very difficult to setup strategy and sometimes getting heavier due to such inconsistent time and fuel data

Maybe the teams practicing in softs are much better than the teams practicing in super soft.

Richard the same driver can sometimes do the same lap time on soft as super soft with this bug. It is nothing to do with better driver/car/team.

I've seen Hards doing faster times than Softs in my practice runs.

I have been seeing the same results when doing practice laps. Can usually spot it after the first 2, save what you are doing and refresh the browser seems to bring the next times you do back into what you would be expecting.

Practice times don't really mean much, more the fuel and tyre wear it is used for.

Hi guys, have the practice times improved to resemble something like before the problem began?

They are better, but still maybe 30% of laps are around 1 second slower for no reason at all.

It looks fixed today

Hi, good evening ... our call was to start tomorrow only at 9:00 p.m. or 8:00 p.m. in case the schedule was not yet corrected as we did. however today had 2 races anticipated one behind the other inexplicably. there was loss of Money, contract and tokens, loss of employee, reputation. out the championship loss. How do you intend to solve the case and indemnify the injured that even the employee has lost. thank you

Stiĺ think there is a problem with times usually at Belgium I can do practise laps of 1.48.4 can't get quicker than 1.49.5 

Yes, it looks like all laps are a second slower now, but at least the times are consistent from run to run
