We started at the beginning of 2015 too, and like you, we appreciate statistics, but the future is there to shape new stats for us. So we are always looking at what we can do next, not what might have been.
In 2016 we completed all days found, and then set about completing all days hidden. We haven't completed our D/T grid yet (17 squares to go) so we are gradually chipping away at that. We love challenge caches so we are always on the lookout for what we have already qualified for, and what we can work towards.
And if you are planning a holiday, why not look to see what you can achieve in various places - an enjoyable trip to Israel this year saw us achieve the lowest caches on earth at -400m, and as a bonus it also got us a lot of our highest caches too at nearly +800m.
Good luck with your future caching! Don't look back!
