                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 741 alloy. Quite the large number.

        <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 741 alloy cost (300 to rebuy the workers, and 441 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 315 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. We can divide that number by 2, to represent our bases, and add those 5 additional seconds to <b>Worker travel time to alloy</b>, for the more accurate loss of 456 alloy (saving you 285 alloy.) <i>Which is much better than not transferring workers!</i>

            <InfoAnswerComponent>
                The Harass Calculator is based on the following calculation.

                <br/>
                <div class="mathContainer">

                            </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.
