I don't want to hijack his blog as he has explained the system and rationale better than I ever could.

If you're at all interested in how riders can be ranked, check out his blog here. It's worth the read; I promise.
On a different note, we're heading to the cabin again this weekend; we're in the middle of a construction project. See you on Monday.
