Should I add the rest of the family's coins to my registry?

I've made gifts of a few certified coins to my stepfather and I'll soon be giving him a few more. I'm also going to be holding on to some coins for my niece until she gets a little older. So far I haven't had any of these coins as part of my registry, even though I'm the only family member with an account. I've been considering adding them because 1 it aids the inventory process and records the certification numbers in the event of theft or other misfortune, 2 it prevents other people from falsely adding the coins to their sets. My stepfather has even indicated that he kinda favors the idea. All the same, I've been reluctant to add the coins because as part of my registry they would inflate my point totals and rank. This may seem rediculous and trivial but it would feel like cheating.

Being too hard on myself? Taking the registry too seriously? Should I just quit beating myself up and add the coins?
