In general, every time our proxy sends a request to a website (asking for an url, .js, .css, image files, etc), our checkers count it as one request. If you are using, e.g., scrapebox, it usually downloads only an html page, not a js, css etc. 

Requests are calculated like this: if you've connected to a proxy and authorized yourself - that means a request. We have no way to determine if the request you send was actually successful, because most sites use https now and everything is encrypted.
