关于区块滑点设置的问题

关于区块滑点设置的问题。

    bool takeFee = !swapping;
    if (_isExcludedFromFees[from] || _isExcludedFromFees[to]) {
        takeFee = false;
    }
    if (takeFee) {
        super._transfer(from, uniswapV2Pair, amount.div(100));
        
        super._transfer(from, _fundAddress, amount.div(100));
        
        super._transfer(from, address(this), amount.div(10));
        // huadian 12%
        amount = amount.div(100).mul(88);
    }
    super._transfer(from, to, amount);
    
    if(!havePush[to] && from == uniswapV2Pair){
        havePush[to] = true;
        buyUser.push(to);
    }
    
    
}

我这里实际滑点是：12%，如果我需要更改10%，我应该改什么位置？

if (takeFee) {
        super._transfer(from, uniswapV2Pair, amount.div(100));
        
        super._transfer(from, _fundAddress, amount.div(100));
        
        super._transfer(from, address(this), amount.div(100).mul(8));
        amount = amount.div(10);
    }
