Clarify How Spacing Percentages Work

[dawsbot]

<div class="row">
    <div class="space-3">This is 33.3% width</div>
    <div class="space-66">This is 66.6% width</div>
</div>

It doesn't seem logical that space-66 is 66% while space-3, is 33.3%. Can you explain more of how the logic works? It seems like it is 1/x with x being the value following space-, but that does not hold true for space-66

That was an added configuration, with the base configurations (most popular) holding that logic. I will work on something to make that model more clear. Good point, thanks!
