Sorry, we had company for dinner so I didn't get a chance
to look until now.
The issue is that you operated for more than six
hours--you started at 2000z and ended at 0411z. That's
over eight hours. You
need to pick the best six-contiguous hours. You can
either do the analysis yourself, or let the checker
decide for you. Just upload multiple times selecting
different start times: 2000z, 2200z, and 2300z. (Since
you had no QSOs during the 2100z hour, that wouldn't be
a good starting time.) Then do one final upload with the
version that scores the best.
My guess (without doing the math) is that 2200z will be
best. You only have one QSO during the 0400z hour, so
that's not likely to be worth more than the QSOs you will
lose for skipping the 2200z hour. And you only had five
QSOs in the 2000z hour--starting at 2000z means you lose
the 11 QSOs during the 0300z hour. The "catch" might be
the multipliers, as I didn't look at that.
