I get pleasing results with this formula:
sub tension { my ($hi, $lo) = @_; $lo or return 0; 2 * log($lo)/log($hi + .1); }
where $hi is the higher number of votes (whichever direction) and $lo is the number of votes in the other direction. Any result above 1 represents an interesting amount of tension, IMO. Here's a table of results:
Hi #Lo #Tension
3 31.9420
8 31.0504
8 81.9881
20 30.7322
20 81.3860
50 30.5614
50 81.0626
90 30.4882
90 80.9240

    That looks pretty good, except it seems to lose the magnitude of the tension. 3 vs 3, 8 vs 8, 50 vs 50 all have similar results.

    (of course that's probably just me visually eyeballing sig figs along a log curve...)


      You're right. My notion was only to distinguish interesting from non-interesting. You regain the magnitude if you drop a log: I'd call < 1.3 low tension, 1.3-2 moderate, >2 strong.

[Tanktalus]: What's so happy about it? :P
[Tanktalus]: ww: your parens don't line up. Sure, perl can look like line noise, but the parens still have to line up. ;)
[Tux]: 1nickt did you build 5.24.3, 5.26.1, and 5.27.4 yet?
Tux now has 284 working versions of perl
[1nickt]: Tux oh yes, have filed reports from them already :-)
1nickt has 44 for one version of one OS ...
[Tux]: good boy :)
[1nickt]: Had to beat on things for a bit to get cpanminus working on 5.8.9, and it just would not go on 5.6.2, so I abndoned that one for cpanm-reporter work. I mean realistically how many people are using 5.6.2 on OS X ? :-/
[Tux]: those 284 are all on my laptop (Linux x64)
