Most light aircraft comps in GA (such as those run by the RFACA) include spot landing comps which are fun - and have variations including glide approaches. Basically they set up a string fence across the runway and then have marked touchdown points at 10 metre intervals with varying score for where you touch down. In these comps they always have someone in the plane checking that you follow proper procedure. The total points for the event is a combination of the inflight stuff ( checklists, heights, speeds, etc) and the score on the touchdown. Its great practice.
