Max speed is way more than that my friend! :-)
In the official Channel on Discord they say it about 10000 a day, autoclicker is tolerated, up to one click every 40ms, or 25 clicks per second. Otherwise you would get an error message, something with suspicouis activity or so...
However, i tried OP Autoclicker, and actually tested what speed would work instead of bliendly going with 40ms delay. Once i set the tool to 1ms delay, it resulted repeatedly into something like 35 cliks per second. works reliably for hours (playing in the browser).
With that you need around 60-80 tickets to complete the event.
