I started answering this question by explaining why it is not important
to *optimize* the number 10 (namely because scores are only ever
compared against other scores, so an overall scaling factor makes no
difference). The factor 10 only has to be large enough to provide enough
dynamic range for the other (adjustable) parameters.

But I think you are asking a simpler question: should we give this
constant a name rather than hardcoding it? I don't see a strong reason
for or against, so I'll give it a name in the next version, as you suggest.

Michael
