Lately my FTF's have jumped so decided to look at giving a group of people opportunity for a combined one. To find the co-ordinates you need to do some simple maths, however, two of the variables are unknown to the CO, so let's see what happens!
Let's start with these 2 variables;
Variable 1 represented as "AB" is your age. If your age is less than 10, add a 0 to the front of it, eg: 08 or if your age is 3 digits please tell me about yourself and use only the last 2 digits.
Variable 2 represented by "CD" is the age of your partner/friend/caching buddy etc, using the same rules as for variable 1.
Now do the following calculation:
Step 1: "AB" X 2 (variable 1 times two)
Step 2: Answer from step 1 add 5
Step 3: Answer from step 2 multiply by 50
Step 4: Answer from step 3 subtract 365
Step 5: Answer from step 4 add "CD" (add variable 2)
Step 6: Using "ABCD" (Variable 1 and Variable 2 next to each other) as a 4 digit number, subtract the answer from step 5
You should now have a 4 digit answer "WXYZ". If not, add zeroes to the left, eg: if your answer is 123, make it 0123.
WXYZ will now be used to determine the coordinates.
The final coordinates are:
S25 (Z)(W).(Z)(X+Y+Z)(Z) E28 (X)(Z-Y).(Z)(Z)(Y+Z)
Good luck!
