Bad beats after withdrawal

[flow]

Ok, so let me just start off by saying that i really dont know if this is true or not, but i just wanna report what i have experienced and hear if any of you have experienced the same thing. I have been playing regularly online for about 3 years and i have been at one of the major online poker rooms for about a year now. I like this room because it has been very profitable for me, but there is a strange problem i just cant get over. I seem to hit long strings of bad beats for a few days to a few weeks after withdrawal. This has happend to me more than a dozen times. To make sure it wasnt in my head i decided to go back through all my records and make a list of the dates of my withdrawals. Sure enough, i see that they all come at peaks in my profits. I usually play tourneys, and it looks like i average a drop of about 20 buy ins after withdrawals. Lately it has been more. Now I'm not crying foul. yet. I have still made a good amount of $, but i just wanted to know has this happend to anyone else out there?
