It seems there may have been at least 82 shows and 426 listed appearances. With 5 people per show, lovegraphs.com and iPlayer have 4% more appearances listed than required (and probably a similar percent of people) perhaps due to listing special guests. The host/captains/regulars have included Robin Ince (Host × 82), Brian Cox (Host × 82).
