I haven't used pairwise summation though. The best solution is to 
partition based on exponent and use accurate integer arithmetics. 
The first function on the link I posted above is accurate in the 
partitions, but inaccurate of the summation of the partitions…

But yes, you can create a lot worse datasets. Kahan only recover 
a few of the lost bits due to rounding.
