Could be the weather is too hot, sometimes I felt the car is going as quick as I expected.

I did a few run to grab some logs tonight, can you guys please kindly advise?

I stop the log take when there was traffic and start again, so the time maybe skipped some minutes in between.

 

You're not recording enough parameters.
Read the Logging 101 sticky record more values and due 3rd gear pulls.
Record new files for each run, don't just start recording and let run on and on.
