So as the problem is more clear now...
There is no evilness, proxystuff, etc that could act as blackbox and hinder you.
The only usual problem some users have are sending the cookies, and rarely a really bad connection.
It´s just a little training challenge to make you play with http requests, nothing mean and hidden.
I suppose there is something on your end that somehow slows your requests down.
If you find out what made this weird timing values (maybe proxy) we are looking forward for feedback
