Generally, if someone wants us to make a change on the Ranch, we would expect them to provide us with a real reason why, beyond "because I want it that way". Sure, YOU think five would be enough, but the next person could say "No, I think it should be seven!", then someone else says "No, seven is too many, I think it should be two".
We had to balance between allowing enough expression without them having too much visual impact.
Some may still prefer none, but three is the agreed middle ground.
At this stage I don't believe we have any intention of changing this number.
- X 3
First shalt thou take out the Holy Pin, then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who being naughty in My sight, shall snuff it.
