In the Blackbox (upgrades), there are nodes for LMB and RMB. Upgrading allows LMB and RMB inputs to click the number down (processing requests). As you rank these nodes up, they are worth more requests per process (click). The rhythm node gives a bonus so that LMB then RMB is worth more, then back to LMB and so forth. Thank you for your time and interest. Be safe!
