Vivosmart 4: Which time must pass between two activities?

Hi,

Which time must pass betweeen two activities so that the second activity is accepted?

5 Minutes are not enough.

For example: Walking 09:00-10:00

Running 10:05 -11:00.

Walking is shown as activity and Running is missing.

Running is not accepted as activity.

That means, 5 minutes are not enough.

I have experienced, that 30 minutes are enough.

What is the smallest time that is enough so that the second activity is accepted?

With regards

S.
