Do people actually sit down and compare collections?
As in: "HA HA!!! The UCM says that I beat you by ONE toy! You loose, fool!!"
I find it hard to get my head around the whole concept of the need to have a UCM since my collection is my own and I don't really care if anyone has a bigger or smaller collection than me.
I know that I will never have a collection in the same league as Griffin's or Gok's and its not due to their massive numbers but because several of the figures and lines in their collection don't hold any interest with me and therefore I will never buy them. That doesn't mean that their collections are any less impressive but it does mean that people like me would never reach that collection size even if we could.
So the Counting method is completly irrelevant to me and any other who does not intend to complete full Transformer lines and/or has no interest in comparing it to other similar collections.
Collecting is too much of a personal thing for most of us. We collect and inclulde what we like. I can't imagine too many people collecting to 'compete' with other and needing to use the Counting Method as the field rules.
