## About The Pull Request I found myself wondering about the best/worse cases of a block of code, this lets me answer that pretty trivially. Also, makes _cost a permanent var, since as is it ends up getting redefined a bunch for no reason. Fun Bonus! [Implements generic semi automated performance testing support](https://github.com/tgstation/tgstation/pull/94529/commits/967ca317db036113174a7f9be8bbe249f91415e6) [967ca31](https://github.com/tgstation/tgstation/pull/94529/commits/967ca317db036113174a7f9be8bbe249f91415e6) I found myself sitting at my desk waiting for the game to init so I could run a proc on a subsystem, then close the game. Figured that was extremely automatable, so here we go
