You're right. My notion was only to distinguish interesting from non-interesting. You regain the magnitude if you drop a log:
sub tension {
my ($hi, $lo) = @_;
$lo or return 0;
$lo/log($hi + 1);
}
my @samples = (1, 3, 8, 20, 50, 90);
for (map {my $x=$_; map [$x, $_], grep $_ <= $x, @samples} @samples) {
printf "%2d-%2d: %3.4f\n", @$_, tension(@$_);
}
__END__
1- 1: 1.4427
3- 1: 0.7213
3- 3: 2.1640
8- 1: 0.4551
8- 3: 1.3654
8- 8: 3.6410
20- 1: 0.3285
20- 3: 0.9854
20- 8: 2.6277
20-20: 6.5692
50- 1: 0.2543
50- 3: 0.7630
50- 8: 2.0347
50-20: 5.0867
50-50: 12.7167
90- 1: 0.2217
90- 3: 0.6651
90- 8: 1.7735
90-20: 4.4337
90-50: 11.0844
90-90: 19.9519
I'd call < 1.3 low tension, 1.3-2 moderate, >2 strong.
