360 Camera Calibration with Forscan

Does anybody who has actually calibrated there 360 cameras using forscan have any tips or tricks? I've been driving around parking lots with fresh lines for HOURS and can't get it to work. On the dash screen , it gets to 6% before timing out. I'll try again and maybe get to 24%. It seems to save progress, and I've gotten as far as 58% but then went back to zero.

Should I drive parallel, perpendicular or diagonally over the lines? Slower? Faster? Yellow lines? White lines?

My cameras...
