I can post an AutoHotkey script under Resources that modify mouse inputs. But first a moderator should clarify what is legal for the speedrun.

Option 1: Ban third-party applications. Varies between people, but I am able to get around 6.5 CPS. Any other option would technically make it Tool-Assisted speedrun.

Option 2: Allow rebinding of right-click to work as left-click. This gives me about 10.5 CPS when mashing both buttons, but also allows you to alternate which finger you use for normal gameplay. This means every single action is still a button-click.

Option 3: Allow rebinding of scrollwheel to work as left-click. This gives me about 12.5 CPS. This is very powerful, as you are easily able to get 10 clicks in a single motion as opposed to having to do 10 unique clicks.

Option 4: Allow rebinding of right-click as a Turbo button. Probably bad, but allows moderators to decide on a CPS that is fair. Either that is 6 CPS so single-click still is faster, 10 CPS so it is easier to verify in runs, or something higher.
