            <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.)

                    Which is
                    much better than not transferring workers!

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

                            </MathDivisionComponent>⌋
                        </LoopEnd>

                        </IndexSymbol>

                <div style="font-family:monospace;">
                    <div>c is CostOfWorker </div>
                    <div>m is NumberOfWorkersLostToHarass, <i>m for [M]otes</i></div>

                </div>
                <br/>
                This logic has since been changed slightly to allow client to enter different travel times per base.
