AdMob广告网络请求比我认为的要大一些

Question

我创建了一个应用程序，其中AdMob标语从头开始（脚本中仅一次）。并且当我关闭应用程序时，我的“ AdMob网络请求”帐户显示例如以前的数字是30，现在是34，难道不应该只增加一个数字吗？

... 使用GoogleMobileAds.Api； ... 公共类GoogleMobileAdsDemoScript：MonoBehaviour {     私人RewardBasedVideoAd rewardBasedVideo；     ...

public void Start()
{
    #if UNITY_ANDROID
        string appId = "ca-app-pub-3940256099942544~3347511713";
    #elif UNITY_IPHONE
        string appId = "ca-app-pub-3940256099942544~1458002511";
    #else
        string appId = "unexpected_platform";
    #endif

    // Initialize the Google Mobile Ads SDK.
    MobileAds.Initialize(appId);

    // Get singleton reward based video ad reference.
    this.rewardBasedVideo = RewardBasedVideoAd.Instance;

    this.RequestRewardBasedVideo();
}

private void RequestRewardBasedVideo()
{
    #if UNITY_ANDROID
        string adUnitId = "ca-app-pub-3940256099942544/5224354917";
    #elif UNITY_IPHONE
        string adUnitId = "ca-app-pub-3940256099942544/1712485313";
    #else
        string adUnitId = "unexpected_platform";
    #endif

    // Create an empty ad request.
    AdRequest request = new AdRequest.Builder().Build();
    // Load the rewarded video ad with the request.
    this.rewardBasedVideo.LoadAd(request, adUnitId);
}

}
