News organisations waiting for results from the US elections may regret putting their faith in a new computer system.
Voter News Service (VNS), the consortium of news organisations that conducts exit polls in the US, has warned that last-minute glitches in a new system could gum up the service.
A spokesman for VNS told the New York Times that it may not know until it is used for the first time tonight how effective the system will be at tallying the collected data.
He declined to elaborate on the nature of the last-minute difficulties, but indicated that the service's statisticians are not yet confident of the accuracy of its statewide surveys.
And they are even less sure about the processing of its national poll of voters' attitudes.
A CNN spokesman claimed that the new system has not yet been tested. "This is the equivalent of a NASA space shot without any test runs," he said. "We are going to learn a few things tomorrow night in real time."
