Measurements of the proton structure function at large x, low Q² display a strong Q² dependence which is usually interpreted as evidence for a significant higher twist contribution. Recent progress in understanding the resummation of large logs, ln(1-x), up to next-to-next-to-leading log order and beyond suggest that the observed enhancement may possibly be due to such terms alone. We study the implications for different theoretical scenarios in the light of novel suggestions for extracting large x information from future measurements at HERA.
