Maybe a clearer evidence like showing your finger/s while clicking the mouse will do , this record can be faked easily. One more thing you can still type into the box after you hit the start button so it is still possible to edit the score,.. Make sense? And after all you didn't show in the video that the time is running or you really start at zero.
i can do 999 clicks in 10 sec.. by simply typing it in the box.. ;)
funny ba?..prang cute lng..hehe
