Wingtip washout is usually very hard to see, but easy to create with minor adjustments to the angle of the airfoils. After much testing, there is a small advantage shown for the "Finch tip" - a wing that tapers to a point, with a slightly swept back tip. That minimizes induced drag by pushing down gently near the wingtips, but without the wasted surface area of washout on a square or rounded tip.
