Abstract
It is pointed out that in the conventional calculation a large part of 〈cos φ〉 in leptoproduction comes from configurations in which the outgoing partons have small pT. This indicates that the conventional QCD prediction for 〈cos φ〉 is not reliable in the experimentally available Q2 regions at present.
