Statistics

Once again I would like to thank the admins for adding extra statistics on user pages (such as: the oldest, the newest, the smallest, the largest etc. coins).

I wonder if it would be possible to add as well some statistics on the average values,such as:
- the average coin date
(says pretty much about the collection's profile)
- the average coin weight
- the average coin size
(these two may be important to plan storage for coins - e.g. sheets, boxes etc.)

Regarding the map, would it be possible to develop a different type of colouring: by percentage of coins available from a respective country? There are countries like Bolivia or Costa Rica that do not mint much; and there are " overproducers" like Canada, Russia or Ucraine, or probably Ancient Rome, where you never have enough.
