That is correct. Since the winter Complex Model requires the use of an RVP of 8.7 psi for both baseline and target fuels regardless of the actual RVPs, the valid range limits for RVP do not apply to the winter Complex Model calculation.(7/1/94)

The original was posted in the Q&A posted on 7/1/94 which can found at http://www.epa.gov/otaq/rfg_qa.htm" See Question ID 3857 for RFG (Taken from the first question on http://www.epa.gov/otaq/regs/fuels/rfg/qa/420r03009.pdf)
Clarify that the valid range for RVP specified in the regulations has no effect on winter calculations with the Complex Model since the RVP is fixed at 8.7 psi in the winter regardless of the actual RVP of the fuel.
