most big hits now storm in at number one then take about 3 months to exit the top 40 - so the chart tends to consist of new entries and tracks down one to six places from their position last week. in contrast, less radio friendly tracks that still retain a degree of popularity in critics circles (lets say the recent Lemon Jelly single 'Spacewalk') enter low down and then drop about 20 places - their chart life is 2-4 weeks compared to a big hit like Shakira's 'Whenever Wherever' which was in the top 10 for 3 months alone.
i think this is as interesting as the chart gets now as i cant recall any wild fluctuations like the ones you describe happening in the top 40 recently. i do remember back in 1996 tho that after the Jacko/Jarvis debacle at the Brits, Jacko's 'Earth Song' which was still languishing in the top 75 then rocketed up about 33 place the following Sunday, hahah
