15 hours, but we know that the storm occurred on the

evening of the 11 , so we conjecture that at the flies

were active at least an hour on the 11th, thus bringing

our PMI to a minimum of 8 days, 16 hours. The actual
PMI, which is unknown, may vary up to 12 hours more
than this calculation due to weather. Students’
calculations may vary by up to a day later.
