I've never seen a count. I keep a list of who and where. Sometimes the game makes a distinction I don't expect and I finish the lifetime wish unexpectedly. A pleasent surprise, unless you have a wish enhancing potion you were saving for that event, then it's clean up on Aisle 7 time: use NRAAS MC+cheats to award the additional LTW points, sell the potion and deduct the money gained by selling the potion from your household account.
Sims are better than us.
