Very good info.  I was surprised to see this:

[data products image [foo-code]]
which is faster than
[data table=products column=image key="[foo-code]"]

I've always named and quoted my parameters because I thought it was
faster.  Is it really faster to position them?

Is PREFIX-calc faster than calc?
