We show that low Q^2 data display double scaling violations which are adequately described by NL ln Q^2 corrections. Scaling violations due to summations of leading and subleading ln 1/x beyond NLO in ln Q^2 are however disfavoured by the data.6 pages, 6 figures, plain LaTeX misprint correctedHigh Energy Physics - Phenomenologytext
