With something volatile like a URL you shouldn't make any assumptions about its length, -- and in this case, nor should you try to derive any meaning out of the various components of the URL path. There is technically no maximum length to a URL, so for storage purposes I would reserve yourself plenty of characters.
Speculation: the numeric portion of the path appears to be epoch time in seconds, equivalent of: "Sun May 02 16:17:07 -0700 2010 " We do offer an API method to determine the avatar for a user by user_id, however you cannot use them to directly render the image -- only to resolve a user_id to a avatar URL string.
