It depends how the pools are dhared - in our club - not everybody pools
so 5p pool, 10p and 20p are shared 50% 30% 20%
30p - 50p - £1 and £5 is the first bird clocked in that pool takes all
so for instance if the 1st bird in the club is only pooled to 5p - he takes 50% of that pool
if the 2nd bird clocked is pooled to 20p
he takes 30% of 5p pool - 50% of 10p pool and 50% of 20p pool
