I can confirm such experience. Usually GPS track is very good however 
from time to time (usually when tangogps is reading tiles) it looks like 
  it's receiving invalid data and the GPS really goes wild.

I have to admit that the GPS works really well and I've seen Paweł 
Kowalak's track which was awesomely accurate! I hope that those 
tomorrow's patches will make the GPS experience even more enjoyable.

Thanks for the great work.
