Refine numbers in headers of summary table

[jwodder]

Closes #15.

cool. Could you actually rerender that header stats so we would see the results -- all the information is there, right?

[jwodder]

@yarikoptic The information is there in the status.yaml files, but the script isn't built for getting information back out of them. Unless you foresee the README repeatedly needing to be regenerated from the status.yaml files, I don't think updating the script to do this is worth it.

ok, it would be a separate development then anyways. Given that it takes days (or weeks) for a full pass ATM I am afraid we aren't to see the effect of this fix for awhile.
