Timing Smart Campaigns

We would like our Smart Campaign to be triggered at certain time intervals after signup. I would like to know if I have my Smart Campaign setup correctly. 

Some background: When a new signup loads data within 24 hours after signing up, we would like to be alerted. We would like to be alerted at different time intervals: 3 hours after signing up, 8 hours after signing up, and 16 hours after signing up. We would like to be alerted via an email notification and a task in SFDC. This campaign is triggered by the value change for the field: App_assets_quantity. We want the smart campaign to look at this field's value 3 hours, 8 hours and 16 hours after signing up, and if it is greater than 0, we want our sales team to be notified via an email notification and a task in SFDC.

Here is how I have the campaign setup:

Smart List:
APP_assets_quantity: greater than 0

Flow:
Wait: 3 hours
Send Email: If App_assets_quantity is greater than 0
        Email: LoadAssetData Send to: sales@risk.io
        Default Choice: Do Nothing
Create Task: 
Interesting Moment: Type: Web  Description: Loaded Assets

Wait: 8 hours
Send Email: If App_assets_quantity is greater than 0
        Email: LoadAssetData Send to: sales@risk.io
        Default Choice: Do Nothing
Create Task:
Interesting Moment: Type: Web  Description: Loaded Assets

Wait: 16 hours
Send Email: If App_assets_quantity is greater than 0
        Email: LoadAssetData Send to: sales@risk.io
        Default Choice: Do Nothing
Create Task:
Interesting Moment: Type: Web  Description: Loaded Assets

Do we have this Smart Campaign setup correctly?

Thanks in advance!
