Nerding Out: Is World Cup Downhill Racing Getting Tighter?
@downhillnirvana: no worries! The opportunity to read, "introduce yourself in bars thusly," made it all worth it, haha. Well done sir.

Nerding Out: Is World Cup Downhill Racing Getting Tighter?
@JmtbM: economics and math major who has been accepted to some of the top PhD programs in the world, who has published economics papers, and who does economic policy research for a living here. You are thinking about this statically and without considering the central tenet of economics: people respond to incentives. For many women, society tells them they are supposed to like dresses, not getting dirty, shopping, dancing, etc. from very young ages. They are incentivized to conform by their parents and other adults, and often do. Thus, their probability of riding bikes is low. As this turns into a stochastic process dynamically, the issue is perpetuated by the fact that little girls' fathers are more likely to mountain bike than their mothers and the girls are more likely to see men riding bikes than women in their environment and on television. (Something very similar has occurred in advanced STEM fields.) From a labor and market perspective, biases have driven a reduced supply of qualified labor (female shredders), and a reduced market. With incentives of medium-term benefits, firms could provide full factory support for every qualified woman, therefore increasing the perceived likelihood of enjoying mountain biking among women, and increasing both the market and qualified rider supply going forward. Because of this potential and the low supply of female shredders, one could argue that female shredders have higher market value than male ones. I should also point out that Tahnee, Rachel, and a local women's riding group got my wife into mountain biking. She talks every day about how much she loved riding bikes as a kid, and how frustrating it was to have her parents and other influential adults disincentivize that because it was "something boys do." She hates that it wasn't until her mid-20s that she rekindled one of her first loves.

@Ttimer: yeah, you could certainly just throw the actual winning time in as a control for that, but a control for track length is only really necessary if we assume variations in fitness level. Using percentage gap naturally controls for track length otherwise. If we think fitness is relatively homogeneous, or that fitness is now orthogonal to skill among top riders, we shouldn't have to worry about track length.

A better approach is probably going to be to regress % gap on year dummies, controlling for total rainfall, average speed (will deal with the fast, non-technical races), soil type, soil type interacted with rainfall, and an indicator for whether rain started during the race. If you only used courses with multiple races held, you could swap some of those other controls with dummies for course.

Bike Check: Christopher Grice's Specialized Demo - 2019 Windrock Pro GRT
@Sugarbrad: I second that. I got to know Christopher and his family last year, and his parents seem more in awe of Christopher's ability than anything else. His dad swelled with pride every time we told him about something amazing Christopher did on the trail.

Video: Danny Hart Previews the 2020 Lousa World Cup Downhill Track
That trail looks like an absolute blast. The last time I said that about helmet cam footage of a DH course, said course turned out to be one of the courses Luca and Neko trained on.... It took me four tries to make it to the bottom of said course without crashing.... Said course broke three collarbones on one jump in an hour on race day....
