Both flood and ab do not require high-precision timers, since they take
many samples and perform aggregate calculations. At a certain calculatable
point, the precision lost from large-grain timers is overtaken by sampling
errors. By increasing the precision we are only changing that crossover
point, but you're still going to have those inherent errors from things
like network latency, processing delays, etc...
