Between runs make sure you bring the motor to a cooling drive unless you are a hot lap type of driver and looking to see your logs for that. But for most roll racing you will have some cool down between. Try to make sure your logging start just a couple of seconds and only a couple seconds after once completing the run. This will help you and your tuner analyze each log properly.
These cars do heat soak so the timing being pulled could be do to that in your later runs, but with the log its hard to tell that. Just my 2 cents.

correction to my last post " Try to make sure your logging starts just a couple of seconds
BEFORE YOU HIT IT and only a couple seconds after
YOU HIT REV LIMIT AND LET OFF (ONLY IF YOU FEEL COMFORTABLE HITTING REV LIMITER) once completing the run"
