I've made a calculator which I'm looking to get some feedback on. I don't think I've ever seen anything similar.
It's purposefully simplified, yet I still think it's quite illuminating.
I'm also being purposefully vague, as the impact is in not knowing what the calculator is about before using it, as that will bias the results. I will put a more detailed description in the comments at a later time.
This calculator was inspired by a conversation with Brenton Mayer at the EA Global conference in Melbourne, 2015.
