The boost grows in a straight line from 1.00× to 2.50× depending on how much xEXIT you lock compared with how much the Office needs for the full boost. ``` xEXIT needed for full boost = a fixed amount × the Office's activation weight boost = 1.00× to 2.50×, in proportion to (xEXIT locked ÷ xEXIT needed) ``` Once you reach the full amount, locking more xEXIT against that Office adds nothing. ## Higher levels need more The amount needed scales with the Office's activation weight. A level 5 Office already earns 3.33× what a level 1 Office earns, so it needs 3.33× as much xEXIT for the same boost. ## It multiplies everything else ``` what you earn = tier's daily rate × activation weight × revenue Growth Hack × boost ``` ## Locking and unlocking settle first Locking and unlocking both settle the Office first. Time before you locked is paid at the old rate, and time while boosted is paid at the boosted rate even if you unlock later. You can't lock right before a cash-out and get paid as if you had been locked all along. ## What else locking gives you Locked xEXIT also earns a share of every swap fee.
