Event does not fire for target scale value when simulating pinching #5

When I use Simulator.gestures.pinch, I expect a pinch event to eventually fire with the scale I specify as an option. So, in the following test case:

package.json:

{
  "dependencies": {
    "hammer-simulator": "0.0.1",
    "hammerjs": "2.0.8"
  }
}

index.html:

<body>
  <div class="test-element"></div>
  <script src="node_modules/hammerjs/hammer.js"></script>
  <script src="node_modules/hammer-simulator/index.js"></script>
  <script src="test.js"></script>
</body>

test.js:

(function () {

    'use strict';

    var element = document.querySelector('.test-element');

    var hammertime = new Hammer(element);
    hammertime.get('pinch').set({enable: true});

    hammertime.on('pinch', function (event) {
        console.log('event.scale', event.scale);
    });

    Simulator.gestures.pinch(element, {
        scale: 2.0
    });

}());

I expect that an event.scale of 2 will eventually be logged. However, the final value to be printed is only 1.9230769230769231. Is this expected or is it a bug?
