NOTE: Only the data that is viewable on the screen is
included in the strike rate. Therefore, you can zoom in
and see what the strike rate is locally, or you can zoom
out for a bigger picture.
Also, when panning with the cursor on the Map Page,
you can zoom in and isolate individual cells. Please
note, however, that strike data is not typically updated
on the Map Page while the panning cursor is on.
Therefore, when the panned map is first displayed, the
data is only a "snapshot" of conditions (as mentioned
above, the strike rate will reflect viewable data only).
