Well, supposedly you/someone replaced those values by different ones, right?
So how did they differ?  Did only the 0.3 ever change or sometimes the whole
thing?  Did it always change symmetrically? ...

I mean the above variable can be used to make super/subscript display in
very wild ways, so I'm wondering if is a feature or a misfeature.
