I don't think it's necessary to list the Roadblock performers, since on all normal legs, we will colour in the name of who did the Roadblock in bold on the far right.
This doesn't really work in this table, I know, but I've been planning to go back and fix legs with multiple Roadblocks by Bolding whoever did the first Roadblock, and Underlining who did the second one.
Remember that, on a Wiki, it's usually preferred to have really simple tables with extensive "Legends" below them. Usually we want to throw out the information easily and quickly to anyone who wants to read
But also, the teams aren't in order anymore. Just like the overall leg placements table, the contestants should be ordered in the order they are "at the end of the day" (Which would be their Pit Stop placements)
