Seems like trying to use expr with var_final causes an error. Any thoughts? - Hivebrain (talk) 16:22, 1 July 2015 (CDT)

From the two minutes I've taken to look into this, I think var_final is created at the very last minute, i.e. after all the standard wiki parsing has been done.

So it's not really a variable at all I guess. I can't... vary. -Black Squirrel (talk) 11:52, 2 July 2015 (CDT)

I'm thinking the best plan might be to introduce loops: https://www.mediawiki.org/wiki/Extension:Loops

{{#vardefine: totalReviews|0}}
{{#vardefine: cumulativeScore|0}}


{{#vardefine: finished|false}}
{{#vardefine: oneLoop|false}}

<!-- while not done  -->
{{#while:| {{#ifeq: {{#var: finished}}|false}} |

    {{#ifeq: {{#var: oneLoop}}|true|
        <!-- if looped once -->
        {{#vardefine: average|{{#expr: {{#var: cumulativeScore}} / ({{#var: totalReviews}} * 100) }} }}
        {{#vardefine: finished|true}} <!-- exit after this loop -->
    | }}   

    <!-- add up scores (this gets done twice) -->
    ...
    {{#vardefine: totalReviews|{{#var: totalReviews}} + 1}}
    {{#vardefine: cumulativeScore|{{#var: cumulativeScore}} + score}}
    ...
    
    {{#vardefine:oneLoop|true}}
}}

no idea if the syntax works but yeah.
