Ok,seeing as all you think it's a hoax ill explane.
It depends how fast your mouse is at recieving clicks and how fast your pc is.
I tried it at my school and the highest i could get was 32
I got hone and did it on mine and i got 60+.
This is because my pc is faster and its got a quicker click and a more sterdy one!
see if this helps.
P.S I cant give a screenchot at the mo because I'm not on my pc . As my routers blown so am on laptop
