Minor Mistake on Tutorial of Using parameters in a class (Python)

[929937690]

On this tutorial link
In the section 3 Build and Run:
It says:
The terminal should return the following message every 2 seconds:
[INFO] [parameter_node]: Hello world!

But since the callback timer set to 1 second, should this part be:
The terminal should return the following message every seconds:
[INFO] [parameter_node]: Hello world!

(Not only with foxy version, the other version also have the same content)

Please correct me if I am wrong! Thank you!
