MANILA, Philippines – A poll watchdog fears chaos in the 2013 elections due to the low accuracy rating of the precinct count optical scan (PCOS) machines during a mock election held earlier this month.

According to, the PCOS was just 97.215% accurate in the mock elections.

That's 2.78% lower than the 99.995% accuracy rating required by law.

The accuracy rate pertains to how the machines will correctly read the ballots on election day.

The group said this should not be belittled because slight differences matter in the local elections where margins are usually small.

In Taguig City, for example, Mayor Lani Cayetano won over Dante Tinga in 2010 by only over 1% of the vote.

But Smartmatic explains those testing the machines and not the PCOS made mistakes during the tests.

Comelec assures the public that the PCOS will still be tested and prepared in the run up to the elections. has other concerns like failures in the bidding for contracts for purchases of other requirements.

But Comelec seeks to placate concerns of a wary public. -- ANC
