  _DIVISOR = 100.
  citizenStatus.points = 100 * timelockMultiplier / _DIVISOR; Make the following change and save 729 gas on average for calling stake citizenStatus.points = timelockMultiplier;

• NeoTokyoStaker.sol#L1155 uint256 points = amount * 100 / 1e18 * timelockMultiplier / _DIVISOR; Make the following change and save 729 gas on average for calling withdrawer uint256 points = amount * timelockMultiplier / 1e18;

[G2] Cache stakerLPPosition[msg.sender] to save upto 2301 gas

LPPosition storage position = stakerLPPosition[msg.sender];
// Update the caller's LP token stake.
position.timelockEndTime = block.timestamp + timelockDuration;
position.amount += amount;
