Project Smiley - MoCache Again

Attention: Changed formulas for starting point and stage 1

Since the original Project Smiley MoCache has been archived a while ago, I thought it was time for a new one. About 35 km of sometimes narrow streets in the surroundings are waiting. Ideally you would combine this multi with a motorbike ride. If you feel sporty, you may also take the bicycle, a lot of elevation gain is guaranteed.
For the best experience I recommend the following GPS routing settings: shortest distance, no avoidances other than dirt roads. It is intentional that you will ride on less usual roads. Still you will have to respect road signs, especially trespassing prohibitions. Be careful (narrow streets) and considerate (small villages). And know have lots of fun.

At the start there's a sign post. Count all the signs attached to the post - not the tree, their corners and colors (white and black count as colors too).
a=Number of signs
b=Number of corners
c=Number of colors

Bearing and distance to the first stop are calculated as follows:
Distance(meters): 253*a*(b-c-5)
Bearing(degrees): 21,3*(c*c-a+1)

I would recomment to commence in north western direction even if your GPS wants to take the other direction.

You'll find a waysign here. Determine shape and colors (including white and black)
d=number of colors
e=number of edges

Coordinates of the next stop
N48 (34000+d*210+e*812)/1000
E008 (36000+d*304+e*896)/1000

Stopover
There are many numbers on top of each other
f=the first two digits of the fourth number from below
g=the fifth digit from below (digit sum: 19)
h=the number in the ninth row from above (digit sum: 12)

Coordinates of next stop
N48 (35000+4*(g-h))/1000
E008 (38000+f*107)/1000

Please give traffic signs precedence over your GPS directions on this leg. You are no residents, really ... plus all legally accessible roads will lead you to the next

Stopover
Likewise you will find lots of numbers here. Two of them have three digits.
j=sum of the three-digit numbers
k=product of the three-digit numbers

Coordinates of next stop
N48 (34100+26*k)/1000
E008 (38100+j*200)/1000

Stopover
We're looking for the year on the well.
l=last digit of the year
m=digit sum of the year

With that you can compute
bearing(degrees): l*7,4
und distance(meters): m*218
to the next

A metal worker has contributed to this structure and has left his name there. Calculate the sum of the letter values of first and last name (A=1, …, Z=26).
n=sum of the first name's letter values
o=sum of the last name's letter values

The final coordinates are
N48 (36000+71*(o+3))/1000
E008 (39000+53*(2*n+20))/1000
