Summary:We reinvestigate the intermittent synchronization phenomenon of coupled chaotic pendula that has recently been a controversy. We propose a simple numerical scheme by which one can easily determine whether the observed synchronization is a numerical artifact of computer analysis or not. By using this scheme, for certain coupling strength regime, we find that the average time taken for synchronization linearly depends on the precision of calculations. According to Longa et al.'s criterion for synchronization, this implies that the observed synchronization is genuine.
