Dania uses "fairplay" which is designed to pair every player of the same caliber with each partner and equal number of times out of each post position. it is not random, otherwise you would not have the level of equality shown in the stats. spikes in numbers are a result of substitutions and the computer will work to equalize those over time. Mr. JaiAlai once wrote that it takes about 3 weeks to rotate through or adjust, but it is a moving chart.
