  Data for D*(2010) meson electroproduction in the range 10 < Q2 < 1350 GeV^2
has recently been presented by the ZEUS collaboration at HERA. We use these
results together with previously published data for Q2 > 1 GeV^2 to test
whether one can distinguish between different theoretical schemes for charm
quark electroproduction. We find that up to the largest Q2 measured, it is not
possible to make such a differentiation. Then we point out the regions where
differences between the various schemes arise.
