Corrected entry: When the first error in Barney's list is discovered, they come to the conclusion that he's only slept with 198 women, so Marshall's previous figure of a 1.195913451538% success rate is slightly off. Marshall says that Barney's "only half a percent less gross than we thought." But using 198 girls in Marshall's equation results in a success rate of 1.18990461538%, which is nowhere near a difference of 0.5%.
Correction: 1.1959% minus half a percent is 1.1899%, ie. fitting exactly with what Marshall says. Subtracting 0.5 wouldn't be half a percent, as 0.5 is a large proportion of 1.1959 (42%, in fact).
