Firstly, thanks to member Atlarge for compiling these statistics. Wish we had an army of folks like him. It's sure hard to fire off opinions when faced with hard facts, lol. ...
Thanks, JL. I haven't been back over here in a couple weeks, so I just now saw this thread.
As has been noted, the 53% figure was for just 59 games in 16 short races to 3. Results from the limited number of streamed matches at DCC events vary widely from year to year.
So I also looked at results (referenced by
NH Steve) for the streamed matches I watched at the last 10 DCC and Southern Classic events. The breaker-won percentage (for the games for which I have that information) varied from 41% to 84% over those 10 events. Small numbers can produce atypical results. But in total it was 389 games in 97 matches, and the breaker won
56% of those games, or about 5 wins for every 4 losses.
As to the skill levels of the players, DCC tries to pick good matches with top-notch players for the stream each round. Success in that objective varies, of course.
The Accu-Stats Make It Happen events are small fields with all top-notch players. The breaker-won percentage in the last 3 (2017, 2016, and 2015) MIH events was 66%, 61%, and 52%. Aggregating those 3 events, we have the breaker winning
60% of the 243 games.
