Yes it's frustrating as the channel 4 team do a good job of explaining the categories etc and I didn't have a clue what factored times were until they explained it just wish they'd stop going to the news etc
Some categories definitely look less "fair" than others as the levels of disability seem to be so different, e.g. why are swimmers with no arms not given their own category, especially as arms are used so much in swimming, instead they were against people who looked more "able" than them I can't remember if they were leg or partial arm amputees but it didn't look fair, as the level of disability was so different
