Strategy question about doing NFL drafts on Underdog Fantasy

So for the NFL playoffs, I see there are alot of 2, 3 and 4 man fantasy drafts for the two game lineup this weekend. I'm pretty new to doing playoff drafts like this.

I'm just wondering if there are any particular days and times that would be tougher or easier to draft in?

I noticed this past Saturday, late night, there was one really experienced player who kept doing the 3 man drafts, and he ended up doing well.

Are late nights really bad and tend to be more sharky? Or are there maybe some bored night owls looking to gamble?

What about earlier in the week vs the night before the games? Would there be more casuals looking to place a quick games the night before? And would earlier in the week mean more of the sharp bettors playing? Just curious on people's opinions.
