Solved Ticks VS Seconds

I have a question about Ticks vs Seconds. Obviously 20 ticks or so are in a second but when scheduling tasks (in plugins) should I set the time as (20 * 1) = 1 sec or just (1)? Does PocketMine convert to seconds or should I go based off of ticks?

1*20, it will run every second if you are using a RepeatingTask.

Yea, 20 ticks = 1 sec.
You need to use ticks. Though, why 20 * 1? Just use 20.

Easier to do 20 * $mySec than irl multiply 20 by $mySec.

So it's easier to calculate 20 * 1 instead of then just use 20?

If I was gonna use 1 second I would just do 20 but most of the time it's more than one second.

Well, we were actually talking about your question, which was basically saying 1 second. We weren't talking about "most of the time".

I apologize for not being more specific and applying my situation to all cases.
