During the first few hours of transmission from 8 to 11 p.m. of May 9, the ratio was constant at around 47 percent.But according to ABS-CBN News Data Analytics Head <a href="https://twitter.com/EdsonCGuido?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor">Edson Guido</a>, the constant 47% ratio between Marcos&#x27; and Robredo&#x27;s votes is due to the fact that all the regions were well-represented during the transmission of results.This is because vote-counting machines (VCMs)—regardless of their location—transmit independently from one another, almost at real time right after polls closed at 7 p.m. on Monday.&quot;Initially, 3 percent &#x27;yong election returns. Tapos biglang nag-37 [percent], the next batch halos 50 na. So ibig sabihin, cumulative yung dagdag na boto... we&#x27;re talking about tens of millions of votes na pumapasok,&quot; Guido said.(Initially, election returns transmitted were at 3 percent, then 37 percent, then the next batch got almost 50 percent. The votes were added cumulatively. We&#x27;re talking about tens of millions of votes transmitted.)The cumulative nature of the counted votes is also a factor in the constant ratio between Marcos&#x27; and Robredo&#x27;s votes, as the new transmissions already add weight to the number of votes they already gained in earlier transmissions.&quot;They&#x27;re adding to the previous total. From 12 million, to 15 million, to 18 million, hindi siya difference. Hindi siya change,&quot; Guido said.&quot;For you to change the ratio of that 50 percent ng votes, the next one that is coming to join this whole 50 percent has to be so drastically different,&quot; he added.<div class="embed-wrap"><figure data-feedback="fb:likes,fb:comments"><img alt="https://sa.kapamilya.com/absnews/abscbnnews/media/2022/life/05/12/transmissions.jpg" src="https://sa.kapamilya.com/absnews/abscbnnews/media/2022/life/05/12/transmissions.jpg"/></figure></div>In this transmission progress table, 4 provinces and 1 city were chosen for comparison with that of the whole country in general: Camarines Sur, Robredo&#x27;s bailiwick; Ilocos Norte, Marcos Jr.&#x27;s bailiwick; Davao del Sur, a Sara Duterte bailiwick; as well as vote-rich Cebu province and Quezon City.The table shows that at during the transmission time, all 5 chosen areas had a similar transmission rate along with the Philippines, which supports Guido&#x27;s statement that all regions were well-represented.Transmissions over time can be seen in Halalan results site <a href="https://halalanresults.abs-cbn.com/transmission-progress">here</a>. &quot;In short, para ka lang nag-survey. Pero &#x27;yong survey mo nga, 2,000 lang eh. Dito, tens of millions. And you&#x27;re capturing the entire thing na well-represented, well-mixed,&quot; Guido said.(In short, it&#x27;s like doing a survey. But in a survey, you only have 2,000 respondents. Here you have tens of millions. And you&#x27;re capturing the entire thing that is well-presented and well-mixed.)The constant 47% ratio is also the statistical Law of Large Numbers at work: &quot;as a sample size grows, its mean gets closer to the average of the whole population,&quot; according to financial website Investopedia.Pulse Asia pre-election surveys consistently showed Marcos Jr. leading by wide margins, with his ratings reaching up to more than 50 percent.<ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/spotlight/05/03/22/pulse-asia-on-disinformation-regarding-our-pre-election-surveys">Pulse Asia: On disinformation regarding our pre-election surveys</a></li>	<li><a href="https://news.abs-cbn.com/news/05/10/22/survey-respondents-rarely-shift-support-pulse-asia-chief">Respondents rarely shift support, Pulse Asia chief says as poll results mirror survey</a></li>	<li><a href="https://news.abs-cbn.com/news/05/02/22/april-polls-of-pulse-asia-topped-by-marcos-pacquiao-overtakes-isko">Marcos tops Pulse Asia&#x27;s final survey among pres&#x27;l bets; Pacquiao overtakes Isko</a></li></ul>Poll watchdog Parish Pastoral Council for Responsible Voting (PPCRV) also had a similar view on the constant &quot;68:32&quot; ratio between Marcos&#x27; and Robredo&#x27;s votes, saying it &quot;does not indicate any irregularities.&quot;&quot;The relatively consistent distribution of votes may be expected to closely mirror the national vote given the random pattern of receipt of the transmitted results,&quot; PPCRV said in a statement.<ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/05/12/22/ppcrv-debunks-6832-magic-claim-in-presidential-race">‘No irregularities’: PPCRV debunks ‘68:32 magic’ claim in presidential race</a></li></ul>Dr. William Yu, an IT director of PPCRV, said the experts they consulted cited the principle of Law of Large Numbers.&quot;The closer you are to the final answer in terms of population, the more it reflects the final number,&quot; he said.He added the experts also looked at the regional distribution for reach transmitted results.&quot;In summary, the computed ratio being similar to each other across different transmission arrivals is not unexpected,&quot; the experts&#x27; report read.&quot;In fact, given that the transmission arrivals can be considered as random samples of the total vote, the computed ratios for each transmission arrival being similar is quite expected.&quot;<figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2034074" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div>
