handicap leagues promote improvement, simple as that. If your already at a peak and have no room to improve, your s.o.l. I personally would like to see how a league worked out with say 50% handicap, as the scratch league i bowl in is barely a league (20 people). i think 50% would give lower average bowlers some chance, but not benifit them too much. ideally, you want to reward the higher average and lower average bowlers equally, but i don't know if this is possible.
