We play using a "central timing clock" for the games at WDC - 45 boards over three days (Friday 9am Friday 5:30 / Sat 9am / 5:30pm / Sun 9:30 am) - and they keep the games moving very nicely. 34 minutes per game year, with adjustments being done on the clock. We had one game go to 1916, but most games are done in less than 6 hours.
We've had two solo wins over the 36 boards played so far.
We had lots of people under 30 at WDC this weekend - including two high school students and one pre-teen (who is ... really good at handling both the complexity and the stress). Don't age us out yet!
Can't wait to get back to Swing 46 someday!
