In case you log at 50 Hz, you should raise the accelerometer sample rate to 100 Hz in LapTimer. It should always be a multiple of the GPS rate. Sample rates on smartphones are 100 Hz and more too. On the WiFi integration. Do you have set the WiFi connection parameters entered in LapTimer's Expert S...

Try to forget about the video stabilization in editing. The result maybe well but will take too much cpu time (aka real time) in rendering progress.

Trackday review should be fun & relax. Buy a Sony active cam, the build-in stabilization function will pay back your money.
