Island Development Rule

In order, to avoid troubles with your neighbourhoods, you should contribute to development of your island at least proportional to how much you are exploring the island.
.
Please donate to your island mines, below is a example of how much you should donate,
If anyone in this alliance is not donating on your island please inform me or ivke.
for refusing to donate,.
.
Formula:
(Upgrade wood required for next level) *(your number of works)] / (The some of all the workers in that mine)= (The amount of wood u should at least give)
.
Example:
to upgrade to lvl 10 a mine of crystal, it requires 40,520
the some of the number of workers, (277+277+178+230+185+110+277+40+40+30)=1644
1644 is to 40520 as 277 is for X
(40520*277)/1644=6827.3
.
If anyone disagrees complain about it as soon as you read. If you complain remember to have a good point.
