PROCESS OBSERVATIONS

The ordering of the individual team member observations for team 6 was different
for each assesor. The original results for these observations have been swapped
from the original (this can be found in the initial version of the data, see
svn cat -r819 process-observations.csv). This was done using photo evidence
taken at the time.

Here are the exact changes:

Peter:
  anti-clockwise: 09:00 -> 18:30, 01:30 (swapped second and third team members)
  unknown: 18:45 -> 00:45
  anti-clockwise: 0:00, 7:00 -> (swapped second and third team members)

Will:
  anti-clockwise: 09:00 -> 05:15 (swapped second and third team members)
  clockwise: 07:00 ->

Florian:
  clockwise: 09:00 ->

The following three times (from Peter's observations) cannot be confirmed using
photos alone. The data may be correct, but may also have swapped the observations
for the second and third team members:
  22:15, 22:45, 0:00.
