Across the grain: between 20 and 30 degrees.
Don't expect a whisker to be completely cut at the "zero" level with the first pass. In general, the beard is reduced in two to three passes, till smooth.
WTG, rather long strokes.
ATG, very short, slightly overlapping strokes.
Others might take a different approach...
