I usually like to use the most I can out of an item. Funny thing is, I never got this item you speak of. But if I did, I would use it like this:
Use the second one 1 second after the first one. The third one 1/2 second after the second one. The fourth one 1/4 second after the third one. The fifth one 1/8 second after the fourth one and so on. The next one waiting just half the time of the previous one. :D
Then I would be happy because I know I used all boosts I could use. :P
