Cool idea. Theres a possible significant blindspot.

The best time to submit a story appears to be 8:30 pm, but that may be because a higher number of stories that were popular during the workday (which is probably when HN gets the most traffic) have been pulled down by gravity enough that newer stories have a better chance of getting in.

But don't those new stories peak during a time that presumably, HN's traffic is at a low? And can peaking at 10PM be enough to carry a story through to the top of the next day's new popular stories?

TLDR: Does being popular in the off-hours offset by the presumably lower traffic to HN?
