>From this I gather that strikes_total is a seven bit number and is going to
role, so I guess it's just a matter of aesthetics, and strikes_total is not
going to be a useful number in the database;
It's only value is to let weewx generate strikes, and weewx seems to have
handled the rollover without a problem. So never mind.
