Troubleshooting: game not matching the calculator?
The calculator models speed, cooldowns, delays, buffs, and turn meter. It does not know about your gear sets, masteries, relics, gemstones, or area bonuses. If your in-game result differs from what you see here, one of these is usually the cause. Work through the list and check each item against your account.
You've checked every item. Any of these that applied to your team can change turn meter or cooldowns in-game in ways the calculator doesn't model \u2014 which is the usual reason for a mismatch. Adjust the affected champion's speed or cooldown in the simulator to account for it, or remove the gear/mastery/relic in question to match the calculator's assumptions.
