Hey Niko,

So just to make it clear for anyone reading the thread - The team bonuses will drop by 2% each day.
Training bonus - bug or not-team-bonuses-rule.jpg

Now, as long as any of the team bonuses is above 0% you will be able to activate it during a live match to gain half of the value as extra.
Explained with greater detail here.

Activating a bonus during LM doesn't deplete the bonus in any way.
