New Handicap System for
Oneballs
Kevin Carter addresses how the players' handicaps should be slewed for
oneball play, given that lower handicap players are at an advanage.
A oneball game is exactly the same as a normal croquet game, but taken as
if each side has already pegged out one ball. Normal croquets, wirings,
etc. still apply. Conventionally the handicap difference between players
was divided by 2 as players only have one not two balls to take around. This
has been modified in the light of experience to be divided by 3 which works
well except when low handicap players are involved
Kevin writes
The old oneball handicap system (one third the difference) was strongly biased
in favour of lowbisquers. Indeed, it was unusual for any nonAclass player
to win a handicap event where oneball is played.
This is because better players make breaks; weaker players rarely can, even
with bisques.
To adjust the balance, experiments with an amended handicap system have been
tried and found to be quite successful. The basis of it is to introduce a 'Superstars
surcharge'  all handicaps below 2 are counted twice.
Examples:
A 6 plays a 0
standard calculation: handicap difference 60 = 6, then
divide by 3 to get 2 ;
new calculation: now 60+(difference between 2 and 0, i.e.
2) = 8, then divide by 3 to get 2.67, rounded to 2½;
An 8 plays a 1
standard calculation: handicap difference 8(1) = 9, then
divide by 3 to get 3;
new calculation: now 8(1)+(difference between 2
and 1, i.e. 3) = 12, then divide by 3 to get 4;
A 2 plays a 1
standard calculation: handicap difference 2(1) = 3, then
divide by 3 to get 1;
new calculation: now 2(1)+(difference between 2
and 1, i.e. 3) = 6, then divide by 3 to get 2;
If there is no superstar then handicaps are unaffected, e.g. 16 vs 4: 164
= 12, then divide by 3 to get 4.
Another way of looking at it is to consider all players with a normal play
handicap of less than 2 move onto a different scale:
Normal Handicap 
Superstar Handicap 
1½ 
1 
1 
½ 
½ 
1 
0 
2 
½ 
3 
1 
4 
1½ 
5 
2 
6 
Remember, too, that handicaps are always rounded to the nearest half. So,
both 1/3 and 2/3 become a half bisque.
We hope this will encourage more attempts at breaks in the belowSuperstar
classes.
