Regarding Wilson’s personality: His flamboyance and occasional indifference to PR protocols will always make him an outsized target of affection when he’s performing well. Conversely, when he’s faltering, his comments/hair/hobbies/etc. will face extreme ridicule. This can be expressed algebraically as follows:

P = Performance [range of 0-10, 5 = average]
WL = Wilson Love [infinitely positive or negative, measured in picocuries]

WL = ( P – 5 ) x Modifier,

where Modifier > 1

I have yet to define this modifier numerically. It might be exponential rather than multiplicative.
