Using experimental data on the imaginary part of the pion form factor obtained from the reaction e/sup +/e/sup -/..--> pi../sup +/..pi../sup -/ up to the inelastic threshold t/sub ..pi..//sub <0/..omega..$ and a simple parametrization for it (respecting QCD constraints) at the range of momenta t/sub ..pi..//sub <0/..omega..$ pi../sup +/..pi../sup -/ data is carried out. The analysis reveals no global incompatibility of the spacelike electroproduction data with the timelike data, claimed by other authors recently.
