How many extra points for having relatives in Canada?

[Peter Rabbit]

Just curious: How many extra points could someone get under the Skilled Worker Class get if (s)he has a relative (half-sister/brother) in Canada?
Also, are the points related to that relative’s socioeconomic status in Canada?

CIC website indicates the following about sponsoring relatives:

Who cannot be sponsored
Other relatives, such as brothers and sisters over 18, or adult independent children cannot be sponsored. However, if they apply to immigrate under the Skilled Worker Class, they may get extra points for adaptability for having a relative in Canada.

Thank you for your help!

5 points assuming that relative is either a PR or a Canadian citizen and is physically living in Canada:

The points are not affected by socio-economic status.
