Has anyone noticed?

I am on the East coast time zone in the US. I have noticed as proven by my game history, there is a remarkable change in win/loss depending on what time of day it is.

I have personally noticed an increase in team losses due to a plethora of reasons, (mostly trolls and the like) after 3:00pm EST. I'm wondering if it's just the kiddies getting out of school start playing or if there is another factor such as a different part of the globe creeping into drunken Dota2 time or something. I would love to hear any theories or experiences.

I would imagine its a combination of both.

I also play US East with a bunch of friends, and we tend to lose a lot more after 12am. My theory is that bad players go to sleep, while the intense ones stay up and play.

I tend to play a on EAST US servers, and notice around 9-11:59 AM EST i tend to win more then playing from 6-12 PM EST. Not sure if there is any reason, i just win a lot more before I go to work then after I get home.

For sure that doesn't count on EU servers: Russians are always awake and either play carry or support without warding and pulling, no matter what time it is. Yeah, there are even good Russians too, but I don't seem to find them in Europe.

Seriously now, I've never noticed it: I usually play in US servers when it's either 9.00-11.00am or 2.00-4.00pm EST in your country I think, but I have never noticed a difference. I will try to keep this in mind and see if there are any differences.
