when creating my UserTrack should I simply play a few bars of every chord I might use or should I instead play every chord progression I might use?

put another way, do UserTracks get sliced up just by chord changes? or do they slice in groups of chords based on what I am using in my new song?

as an example let's say I create a UserTrack with a bar of G, a bar of C and a bar of D. will I get better results if I instead add the following,

1 bar of G followed by 1 bar of C
1 bar of G followed by 1 bar of D
1 bar of C followed by 1 bar of D
1 bar of C followed by 1 bar of G
1 bar of D followed by 1 bar of C
1 bar of D followed by 1 bar of G
