if you run it in it's own window and it's the last targeted window, it will keep whatever your timer is
(if I'm understanding it correctly)
I also run hitfinder at 3 seconds. (yes, hitfinder is on worker.mturk, but I swear I still get too many PREs when both run, idk, idc ¯\_(ツ)_/¯ )
this causes the two of them to sometimes pull too many page requests, giving me PREs
since I very rarely run something that's older than two days, I never really have more than 15 running at a time, usually
therefore, having it in it's own tab, a window that is not the primary focused within the browser,
leaves it at a 1 second interval timer regardless of what I set the timer for, since I have stopautoslowdown enabled
1 second intervals aren't terrible, and have still been largely successful for me.
