As far as I can tell Covent Garden[1] to Embankment needs one change at either Leicester Square (Piccadilly then Northern) or Piccadilly Circus (Piccadilly then Bakerloo). Not sure how you'd get three changes beyond either a bizarre route (CG-> Holborn -> Oxford Circus -> Victoria -> E?), or counting entering and exiting the stations at either end as a change. The fact that the tube map makes stations in the core appear further away then they are is an issue (see also: Lancaster Gate / Paddington). It's a bit of a tradeoff, as a geographical map makes the dense central London bits tiny, but a systematic map exaggerates the distances between those same stations. I suppose having a geographical map for the core, and a systemic map for the outer areas might be an idea, but having two maps might lead to a whole load of "now you have two problems" situations with regard to which map to use in which situation etc.[2] The current map isn't ideal, and could probably use some heavy tweaking, but some problems are hard to solve (beyond geographical / systematic you also have the the general "too many stations" issue from TfL expanding its empire). [1] At least once the "Exit only until November 2015 etc." goes away. [2] There is already a second map that shows all mainline stations that take Oyster cards as well as just TfL stuff. It is insane. So a geographical map is probably a third problem.
