Audit shows nearly 100% accuracy for poll machine

Posted on June 17, 2013

TACLOBAN CITY -- A random manual audit of the votes cast in Eastern Visayas last May showed that the results of the precinct count optical scan (PCOS) machines were nearly 100% accurate, an official said.

Veronico G. Petalcorin, officer-in-charge of the Commission on Elections (Comelec) in the region, said ballot boxes from eight randomly selected areas in the region have so far been checked and showed 99.9% accuracy in the PCOS count.

An audit was conducted on June 7 on the ballot boxes coming from the clustered precincts in Barangay Mada-o, Kawayan in Biliran province; Bunawan, San Isidro; Poblacion Zone II, Javier; and San Isidro, Sta. Fe -- all in Leyte.

A similar check was also conducted in Barangay Poblacion, Pinabacdao and Cagtoto-og, San Jorge in Samar province on June 10 as well as in Barangay Salhag, Rosario and Dapdap, Las Navas in Northern Samar on June 11.

"Based on the manual audit results, there was no discrepancy in the votes cast using the PCOS machine. It proves that there was no problem with the PCOS machines used during the elections," Mr. Petalcorin said.

All ballots were submitted to the Comelec central office’s random manual audit committee (RMAC) for further verification and final audit, he added.

Other ballots that need to be counted are from Barangay Malazarte, Matag-ob and Bocawon, La Paz in Leyte; and Barangay Consolacion, Sogod in Southern Leyte.

Mr. Petalcorin said the final audit report will likely be released on June 25.

Under Republic Act 9369 or the Automation Law, the random manual audit is required in at least one clustered precinct for every congressional district.

The law also says a 99.995% accuracy of the PCOS count should be met.

In the 2010 elections, the Comelec in the region selected 60 clustered precincts and the final audit results showed that the polls were 99.6% accurate. -- Reyan L. Arinto
