Update. The root cause is in the original recording. It looks like your 10 Hz GPS delivered corrupt data for the spot all the spikes originate from. I assume the interpolation applied during VBO export is running in precision issues triggered by the specific pattern shown in the "bad spot". You can ...

This looks like some interpolation problem. When zooming into the top point of the corrupted CT diagram, you will see something like this: Screen Shot 2019-08-13 at 10.34.05.png This means there are some rows included in the VBO which have wrong polar positions and add this long extends to the South...

Please export exactly this lap (not multiple laps) to HLPTR and send it to Harry@gps-laptimer.de

To get valid acceleration data, you need to position the phone in one of the orientation shown in illustration #4 of Quick Reference. it will work in other orientations too, but lateral and longitudinal acceleration will be crap. Furthermore, the phone needs to be on and LapTimer in foreground, so p...

Does the data look fine within LapTimer? In case it doesn't, the export will neither.
I can't check the file manually, it is too big. CT is quite fragile with the VBO format, there is no official documentation either.

Yes, one of these.

Undo is almost absent on mobile devices. LapTimer will always prompt you ahead of destructive actions. In case you have created a backup, please restore that. Otherwise, goto Administration / Databases and check if you see an automatic system backup with a sound number of laps you can restore.

You will need to adjust the video sync manually.

Select the joined lap from Lap List, goto Video Preview, in the Video Details dialog coming up, search for the sync information in the bottom and select it. Follow instructions to adjust the sync.

Hello, We have found the problem with AMP... The problem is about the third split shortly ahead of s/f. Whenever LapTimer hits a tigger (like split or s/f), it pauses detection for 2 or 3 seconds. So the faster you driver, the higher the probability s/f will be missed because LapTimer is paused from...

Hello, The technical functions have been moved down the view hierarchy. All the recalculate functions are now located in LapTimer ‣ Analysis ‣ Lap List ‣ any lap ‣ Fixes. Press the second icon in the bottom to get a list of recalculations available (including tire temperature simulation). On AMP: ac...
