Improve smooth error handling

[Konboi]

In the raw profile, we used dict['key'] method with or <default value>. However if it doesn't define a target key, a default value won't used and KeyError: '<TARGET KEY' exception will be thrown. So, I fixed to use .get(<KEY>, <DEFAULT VALUE>) instead of dict['key'] or <DEFAULT VALUE> style.

And, fixed when the user set duration as string type, we'll covert it to float (number)
