On tying ties

When I was in high school, I had a mental block about tying ties. My dad was really good at it, so instead of putting forth effort myself to learn how to do it, I just had my dad tie my ties and then I kept them in my closet pre-tied. At some point during college, I had either gotten a new tie or I had accidentally untied one of my pre-tied ties while taking it off and I found myself needing to tie a tie myself. Naturally, I did a quick web search to see if there was anything online about tying ties. What I found is really interesting and has helped me a lot over the years, so I thought I would share it with you. Continue reading ‘On tying ties’

2008 Pirates’ Season: Another Exercise in Futility

Well, the regular season is over and the Pirates’ season can be summarized as follows:

The Pirates are now the team with the longest currently active streak of consecutive losing seasons in any major American sport. The last year they had a winning season was 1992, which is more than half of my lifetime ago. If they don’t have a winning season next year (which, let’s face it, does not look very likely), they will take over sole possession of one of the most disgraceful records in professional sports.

As I mentioned in my post on the sports graph paper I developed, I have been charting the Pirates’ win fraction for the last few seasons. With this year’s season at a close, I can summarize my findings: despite a bunch of changes in the Pirates’ organization over the last few years – a new GM, new manager, new coaches, and many new players – the Pirates’ final win fraction has not changed significantly over the last four seasons. Specifically, they have finished with a win fraction of between 0.410 and 0.420 in each of the last four seasons. That means that over the last 4 years, they have either won 66, 67, or 68 games per season. Evidently, all the changes they have made have done precisely nothing to help the team win.

From the graph above, it’s clear that despite vastly different performance early in the season, the Pirates always manage to regress back to approximately 0.415 by the end of the year. If you’d like to play around with the data I used to create the above plot, take a look at this tab-delimited text file of the Pirates’ total wins and win fraction vs. number of games completed. You might have fun or you might get depressed. You’ve been warned.
