That makes sense. The point I’m trying to make, though, is that the choice of how to do the conversion from CO2/kcal to hours/kcal is probably the most important bit that drives the results. I’d prefer to make that clearer to users, and get them to make their own assessment.
Instead, the WPM ends up coming up with an implicit conversion rate, which could be way different from what the person would say if asked. Given this, it seems like the results can’t be trusted.
(I expect a WPM would be fine in domains where there are multiple difficult-to-compare criteria and we’re not sure which criteria are most important – as in many daily decisions – but in this case, it could easily be that either CO2 or suffering should totally dominate your ranking, and it just depends on your worldview.)
You are right. I spent time thinking about your comments and I agree that making the tradeoff clearer is one of the most important improvements I can make. Thank you for bringing it out.
