Notes
These timings were made using Javascript Date.getTime() running in a web-browser on the participants own equipment, and researchers should read
Resource 501 before making use of this data. Timings which have obviously been affected by the issues discussed have been flagged as Invalid.
Coding 485 defines 1 special value:
- -1 represents "Invalid timing recorded"
