RRV is not AFAICT used anywhere else for political elections.  Even
the web page you produced previously just produces one example of RRV
having been used elsewhere _at all_ and that's for selecting Oscar
nominees for one particular Oscar category.

SPI should adopt a system widely used elsewhere.

STV is the only widely adopted proportional voting system suitable for
SPI (the others are supplementary/additional member systems, and party
list systems).

STV is used:

In the UK:
 * The Northern Ireland Assembly
 * Northern Irish local government elections
 * Scottish local government elections

In Australia:
 * The Australian federal Senate and federal House of Representatives
 * The legislative assemblies (etc.) of all the states etc. (New South
   Wales, Victoria, Queensland, Western Australia, South Australia,
   Tasmania, the Australian Capital Territory, the Northern Territory)
 * (Many?) Australian local councils

(and then I got bored.)

SPI should adopt STV.
