Our experience with Distance Handicap Tasks is that they dramatically
reduce land outs, especially with the lower handicapped non turbo gliders.
Easy to set, easy to score, see
www.handicaptask.uk for details. Also take
a look at

for an example. I directed this comp over a weekend. The only land outs
were two pundits in JS1c's pushing too hard.
