In the BJ conditions charts at the end of BJF there is a form for players wishing to report on local conditions. What does the 'Tables Open' section mean, exactly? And how is it useful?

I would like to submit a report on current conditions in London. Has this new 'Trackjack' feature made the printed BJF results obsolete?
I am glad to see the listing for O/U at the Park Tower has finaly been removed, incidentaly; they have not had it for years. However, the Park Tower is still listed as being in 'Knightsbridge'.
It is in London. K-Bridge is a district of London.
Does anyone care? I only ask so as to report needed info.
