Regardless of DWPS & UWPS, and Crosspicking, there is another variable I’m looking at with my playing. It is the angle of the stroke with relation to the nut and bridge. For example, with a downstroke as the pick crosses the string, it gets closer to the bridge, and with an upstroke it gets further away from the bridge. Or vice versa… , or it can be exactly perpendicular to the string.
My stroke is angled so that a downstroke moves closer to the bridge, It crosses the string at almost 45 degrees away from the perpendicular, but not quite.
Does this variable even matter?
