The Mark IV uses a linear encoder to obtain pedal information, which means that every time the pedal sensor passes another mark on the encoder, it will generate a message to tell the processor where the pedal is. This means that every time the processor receives another position message, it will generate a corresponding MIDI message. On playback on a Disklavier, this gives you the half-pedalling effect, on an electronic keyboard, it generates a lot of unecessary information.

Using Cakewalk on a normal midi file the pedal symbol is there when depressed once or so in a bar... but with a MK4 MIDI file within cakewalk there are like 50 of these symbols all mashed together in one bar if the pedal is used.
