Social Group Similarity - How big is the range?

[Wiwyum]

Howdy,

So I'm looking to buy players that all have a similar personality type. However, I don't know what the range is. To be clear, here is an example:

 

Model Professional - Professionalism: 20

Perfectionist: - Professionalism: 14-20

 

If my team is made up of only model professionals (which will have 20 professionalism), and I then decide to buy a perfectionist (with potentially 14 professionalism) would this difference of 6 between the two put the perfectionist in a different social group? How far apart can these numbers be before they are no longer considered to be of similar personality types?

 

Thanks for any help
