The stuff produced by clocks.
And yes, of course, boffinry should be measured in deci-Pykes.
This would allow some fine grained distinctions to be made. For example, I would claim a couple of deci-Pykes, one for my fabulous dress sense, the other for my habit of actually reading footnotes in academic reports and then going and checking upon them. But most certainly not enough proper boffinry to reach a full and glorious entire Pyke. Richard Feynman might achieve a deca-Pyke.
