To make it clear, I was responding to bb's quote of his post:
I assume you are giving each pool a table of random block find times (randomly generate a high-precision round percentile 0% to 100%, turn that percentile into number of individual hashes required using correct math, turn that into times using hashrate), and then are simulating the switching and share percentages earned.
in which deepceleron does not make any mention of the type of random number distribution he or she thought would be used.
