  • Dan Clark is not available the first day (July 13), so any other day is preferred for Import Assertions.
  • Caridy, Leo preference to present at the second half (11PM East Time) of the first day, but also the second half of other days.
  • Philip Chimento not available on the final day, nor in the first hour or so of each day
  • Jamie Kyle is not available on the first day (July 13), so any other day is preferred for "Accessible Object hasOwnProperty".
