How to edit colonization equation?

[unmerged(54588)]

I was wondering how to edit the values in the colonization equation, primarily the "number of colonization attempts penalty." I can't seem to find how to do this...and i've been looking for about 3 hours

That value is defined in the scenariofiles as colonialattempts = somenumber
In example in my 1419 POR file it reads like this:

country = { 
    tag = POR 
	ai = "portugal.ai"
    colonialattempts = 10 
    colonialnation = yes 
    major = no 
(...)

You can edit that value to any other positive integer. Apparently putting it on 20 or higher removes the penalty.
