Okay, you got me but it made be go back and test myself. I misread the text on the test screen, not realizing that it was testing in 10 second groups. I ammended that and tested at 12 clicks per second, much faster than I'd expected. Not shabby for an "Octopus." "Cheetah's" typically click 13-15 clicks per second and that's not really very much lower than your assertion that "20 clicks is not humanly possible." So much for substantive evidence.
In all of your arguments to date, you also completely ignore the fact that there are programmable mice/mousepad/joysticks that enable the user to set up an auto-clicking macro at "X" clicks per second. Does that equal cheating? It's generally accepted that a game "cheat" is breaking into the coding and an "exploit" is finding a loophole in the programming (code) enabling the person using it to augment or increase an action, such as rapid mouse clicks. It's also generally accepted that exploits are available to anyone so it levels the playing field, meaning all of those using the software, i.e., game, could do it if they wanted to.
So, yes, based on those generally accepted guidelines, a mouse/mousepad/joystick that was programmed with such a macro constitutes more of a cheat than an exploit BUT isn't the real question whether or not the developers think so as well? What if they've investigated a purported 'cheater' and found no evidence to support that assertion? IF a human could do, then it's not a cheat by pretty much any definition in the industry.
I personally wouldn't risk my gaming account on such an "if" but many do and who's to say they're wrong? (Yes, I know you do....but you don't seem to define cheating by any standard I've encountered as legitimate in the industry). At the end of the day it's about providing the developers - Inno - with proof they can actually do something with. Yes, counting mouse clicks, per se, is a fine start but I'm afraid you're going to have to offer more than "it was fast" and "it's not humanly possible" to get their attention.
I'm slow as molasses in the winter time and I came pretty darned close to top-end on the click test. Imagine what I could do with a little more practice.
