Charging a trophy has the same affect no matter what your talent. Having more than 2 friends charge your trophies in a day is a wasted charge, as you can only collect twice, if you happen to be able to collect exactly 12 hours apart - otherwise you end up only collecting once a day on most days.

Many players charge trophies as it is the easiest/fastest way to get through visiting, and I think many don't realize that their friend is not getting any benefit. I only charge trophies on my inactive/zombie friends to get the rewards and CIs for myself. On my active friends I always charge rooms, but there are so many rooms, that I am sure most of my charges to my friends, and my friends' charges to me are lost. As someone has said before, the charges disappear after 48 hours.
