Node Tensionby mojotoad (Monsignor)

Recently, buried in Front Page with Negative Rep.. we had a discussion regarding the concept of a Node Tension value display for any particular node.
The basic idea would be to illustrate the relative contention over a node rather than the tally of plus and minus votes. This would be a measure of how controversial the node is rather than any absolute measure of its generated approbration or opprobrium. This value would be visible before actually voting on the node.
I provided the following illustration:
In response, giulienk provided an interesting attempt at an empirical formulation of the idea. I played with it, but it was not quite satisfactory, especially since it seemed coarse-grained at lower magnitudes.
The core issue is capturing the magnitude of opposing votes. 100 positive votes and 0 negative represents no contention. 5 positive and 5 negative represents some, but not huge contention. So I employed Occam's Razor on the formulation and decided:
Formula: $t = min($plus, $minus) * 2
Recasting the original example, this would yield:
This accurately captures the magnitude of contention without revealing, beyond bare necessity, the actual votes cast.
