what a contract may be worth after a chosen number of hours
An option after a few hours is driven far more by where SPOT goes than by
time decay, so the scenario table varies spot and holds implied volatility
fixed; the empirical panel shows what comparable options actually did, which
carries real IV and spot moves. Read them together, not separately.
