Right Place Right Time - S4-E22
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%.
Right Place Right Time - S4-E22
Corrected entry: At the end of the episode when Ted goes around hugging people whilst holding the yellow umbrella, he isn't holding the umbrella when he goes to hug Barney at McLarens.
Correction: There is a place to check umbrellas at the entrance of the bar, so Ted must have checked it like everyone always does. Notice how even when it is raining, no one has umbrellas in the bar.
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).
