2013 America's Cup: Race 18 and 19 of 17

The 2013 America's Cup is a best 9 of 17 series of races. As of yesterday, the Americans have won five races compared to the New Zealanders' eight, but the American team started with a two point penalty due to cheating during the 2012 warmup events. so the score stands at NZ 8 / USA 3, with 13 of 17 races sailed. While it seems most likely that NZ will get their final win soon, what will happen in the improbable event that the Yanks win the next four races, bringing the score to NZ 8 / USA 7, with all 17 races sailed? Will additional races be scheduled? -- ToE 13:15, 21 September 2013 (UTC)[reply]

Our article isn't quite up to date, though it already features races 15 - 17 as "if necessary". America's Cup's home page announces: "Sunday, Sept. 22: Race 18* (1:15 pm PT), Race 19* (2:15 pm PT) (*If necessary)". ---Sluzzelin talk 14:08, 21 September 2013 (UTC)[reply]

Sorry, the schedule I linked to [1] actually doesn't quite match the table in the article you linked to (2013 America's Cup). I don't know if Wikipedia is counting races differently. ---Sluzzelin talk 14:15, 21 September 2013 (UTC)[reply]

Thank you. That certainly answers the question, that the race series is the first to 9 points with a possibility of 19 races. It appears that the WP page on the race series is more up to date than the official page, and the race number discrepancy comes from the postponement of the 2nd race on the 19th and the abandonment of the first race on the 20th, which is not yet reflected on the official page. -- ToE 14:24, 21 September 2013 (UTC)[reply]

Last time I checked the official schedule linked from our article did include a race 18 and 19 with a footnote mentioning the penalty. I do have some sympathy for your confusion, even here in NZ, surprisingly for all the talk about NZ needing to win 9 and Oracle needing to win 11, few people seemed to actually explain that the schedule would be extended to 19 as needed (I found out from our article it would be up to 19 I first heard anyone mention it a few days ago I think just after NZ reached 8). In fact I distinctly recall at least one source which said it was first to 9 or best of 17 and also mentioned the penalty with no explaination of what would happen if it reached 17 races without any team having 9 points (but barring further penalties or whatever, one team would be on 8 and one on 7 so if it was the best of 17 one would seem to be the winner which of course could have happened 9 races ago). Similarly last time I checked which was a while ago but was IIRC when the races had started and definitely after the penalty, the TVNZ schedule and possibly some official schedule I came across at the same time only listed 17 races. I guess the rules were clear that it was first to 9 so for those in the know it didn't need explaination that it would go past 17, but I also suspect some of these less knowledgable writers or commentators were just mathematically challenged and so didn't appreciate why some explaination would be helpful surrounding the best of 17 vs first to 9 issue.

key

Hello, these two songs have a different key ? 198.105.120.239 (talk) 21:41, 21 September 2013 (UTC)[reply]

The second one is lower. It might be due to a speed difference in the video. Bubba73 ^{You talkin' to me?} 00:31, 22 September 2013 (UTC)[reply]

The second version of the song is slowed down by approximately 3%, affecting both the pitch and the duration of the song. The second version is out of tune (flat). I checked with Audacity that I could get the two versions to be both in sync and in tune by speeding up the second one. The key of the first version is F#. F#, when played on the high E string of a guitar, has a frequency of 370 Hz. I had to detune my guitar such that F# corresponded to 364.9 Hz, to be in tune with the second version. If my late-night calculation is correct, that should mean that the second version is off by 25 cents (364.9 * 2^(25/1200) ≈ 370). The second version has also been heavily compressed and then normalized to max volume. --NorwegianBlue^talk 00:47, 22 September 2013 (UTC)[reply]

I think 3% should be about 50 cents. 100 cents is 5.946%. But actually 370/364.9 is about 1.4%, about 23 cents. Bubba73 ^{You talkin' to me?} 02:02, 22 September 2013 (UTC)[reply]

You're right that the numbers don't fit, I was about to post a correction. I repeated the measurement of pitch difference again, listening a lot more carefully (it's night here, can't play loud). To be in tune with the second version, I needed to detune my guitar such that F# corresponded to 361 Hz. This means that second version is off by 43 cents (361 * 2^(43/1200) ≈ 370). There still is a discrepancy between the speedup (factor=1.0303) and the frequency-increase my ear perceives (factor=370/361 = 1.0249), but within the margin of error of the methods used, I suppose. --NorwegianBlue^talk 02:50, 22 September 2013 (UTC)[reply]

Yes, that's about right. The original calculations didn't quite match up is all. Bubba73 ^{You talkin' to me?} 03:37, 22 September 2013 (UTC)[reply]

Is it impossible to set the second song's key with instrument ? 198.105.120.239 (talk) 01:21, 22 September 2013 (UTC)[reply]

With some video editors you can adjust the speed, thus bring it up to par. Bubba73 ^{You talkin' to me?} 02:28, 22 September 2013 (UTC)[reply]
