-
-c

BUGS AND CAVEATS
The time-period given with the overall summary (
option -o) is sometimes misleading.
The program displays the maximum timespan
from the given
subset, while the availability rate is calculated
from the records available in the input
database. Only the times where previous runs of
estimate_data_availability added a record are taken into account.
