How much tougher are day games than night games??

[Jman28]

I play only on party, and I find that I usually play at night. I played a couple during the day today and found the game to be much tighter. Players took forever to bust out.

With the night games, I've had an ROI around 50%. I didn't place in the two day games today, which isn't the point I know. I'm just wondering if the games really are much tougher, and if I'm only programmed to beat weaker games.

this is party $55 SnGs by the way.
