Obviously this is a well discussed subject with many passionate opinions, so I'm just gonna drop this analysis file here and let you all tear it to shreds before I weigh in. Its as factual as can be, but some of you will have better data; its as unbiased as can be, but you all are biased; its inconclusive in summary, but the numbers tell a story.
Yes, I'm a nerd, and numbers matter... but hopefully not just to me. If this is a product I can improve with better data for better decisions for my fellow new-hires, then pass that on. (No I'm not gonna run the math for every airline, hire date, person... its all about me really).
Cheers!
