Consulting the Codex…
RS3 · Skills · Activities · Quests
The Codex keeps its readings for 400 days, so you can go back that far, to the first day it read IM City Wok.
Every common prerequisite the site could check is met for IM City Wok. Gear, abilities, perks and relics decide the rest. Quests need a public profile, so the quest checks are left out of the score.
