                What is this tool?
            </InfoQuestionComponent>
            <InfoAnswerComponent>
                The Harass Calculator allows you to calculate damage done to an enemy alloy line. For example, if you
                 were to attack with Ichors, and kill 6 enemy workers, you can set the <b>Number of workers  lost to 
                    harass</b> to 6. This would determine a loss of <span id="exampleTotalAlloyLoss">@ExampleTotalAlloyLoss</span> alloy. Quite 
                 the large number.
            </InfoAnswerComponent>
        </InfoBodyComponent>

        <InfoBodyComponent>
            <InfoQuestionComponent>
                What can I learn from this?
            </InfoQuestionComponent>
            <InfoAnswerComponent>
                Well, let's assume you lost a full alloy line of workers, and have to take that 
                @ExampleTotalAlloyLoss alloy cost (<span id="exampleWorkerCost">@ExampleWorkerCost</span> 
                to rebuy the workers, and <span id="exampleMiningTimeCost">@ExampleMiningTimeCost</span> in lost mining 
                time.)
                <br/><br/>
                If you were to set the <b>Number of townhalls you have</b> to 2, the calculator will consider worker 
                transfer micro. Allowing you to cut the total cost by roughly 
                <span id="exampleTotalAlloyLossDifference">@ExampleTotalAlloyLossDifference</span> alloy. However, that number isn't 
                entirely accurate, you are also going to have to bump up the <b>Worker travel time to alloy</b> to account for the time it takes the transferred workers to arrive at the decimated alloy line.
                <br/><br/>
                Let's say it takes 10 seconds for workers to transfer from your second base. Let's enter that for the
                second base travel time for the more accurate loss of <span  
                id="exampleTotalAlloyLossAccurate">@ExampleTotalAlloyLossAccurate</span> alloy 
                (saving you <span id="exampleTotalAlloyLossAccurateDifference">@ExampleTotalAlloyLossAccurateDifference</span> alloy.) <i>Which is
                 much better than not transferring workers!</i>
            </InfoAnswerComponent>
        </InfoBodyComponent>

        <InfoBodyComponent>
            <InfoQuestionComponent>
                Can I see the formula for the calculation?
            </InfoQuestionComponent>
            <InfoAnswerComponent>
                The Harass Calculator is based on the following calculation.

                <br/>
                <div class="mathContainer">
                    <div> =c*m+r*g*(t+l) + </div>

                            <MathDivisionComponent>
                                <Dividee>m</Dividee><Divider>a</Divider>
                            </MathDivisionComponent>⌋
                        </LoopEnd>
                        <IndexSymbol>
                            <i>x</i>
                        </IndexSymbol>
                    </MathLoopSumComponent>

                    <div style="width: 132px">g*<i>x</i>*(t+l)</div>
                </div>
                <br/>
                <div style="font-family:monospace;">
                    <div>c is CostOfWorker </div>
                    <div>m is NumberOfWorkersLostToHarass, <i>m for [M]otes</i></div>
                    <div>a is NumberOfTownHallsExisting, <i>a for [A]cropolis</i></div>
                    <div>r is m mod a is LeftOverWorkersToProduceCount()</div>
                    <div>g is AlloyMinedPerSecondByWorker</div>
                    <div>t is TimeToProduceWorker</div>
                    <div>l is TravelTime</div>
                    <div><i>x</i> is workerProductionIndex</div>
                </div>
                <br/>
                This logic has since been changed slightly to allow client to enter different travel times per base.
