Quoted from Fanatic:I can help.
A friend of mine devised a math formula to help me determine whether I have "enough" pins in my collection.
The formula is as follows:
The amount of pins necessary to equal "enough" is a function of (N + 1)
Where N = The number of pins Currently in possession
Therefore: (N+1)=The correct number of pins
As you can see, the formula is quite simple. You may use this formula for bicycles, fly rods, skis,.........etc.
I hope this helps.
There's another formula I have seen in action as well that brings a new variable into the equation
X = number of machines you THINK you have space for
Y = ACTUAL number of machines you need to buy to properly fill the spae
N = number of machines owned
Y = (X-N)+1
As you can see, the number X continues to climb as, just when you think you can't fit anymore, you buy another one, and poof! There's the room!
The downside of this equation is that if/when your wife/husband/family deserts you and leaves the house empty, X climbs astronomically and the empty void left behind will, literally, be filled by pinball machines.
Wait did i say downside....
