I didn't say you were wrong--sorry--I just didn't understand. Ok I think you mean the 14 "strategic points" on this map you linked, every two of which will give 1 bonus.
So lets just look at three for now, call them A B and C to not confuse bonus names with the bonus value.
Bonus for AB=1 AC=1 BC=1. To make sure anyone with all 3 pairs doesn't get all 3 bonuses and still only gets 1, you add a negative bonus: ABC=-2
Now anyone with A, B and C will receive: bonuses for ABC, AB, AC, and BC: -2+1+1+1=1 as required.
This is done for every possible trio e.g.. ABD, AFG, BDE, etc. They will all be bonuses of -2
(Put in the numbers, you'll see straight away why. It can get a lot more complex when you're introducing different values though; the negative bonuses will vary a little.)
Now that the trios are done, then you look at every quadruple: ABCD for example. We now have to consider:
AB, AC, AD, BC, BD, CD, and ABC, ABD, ACD, BCD.
The sum of the above is 6(1)+4(-2)=-2. To correct this we introduce a bonus: ABCD=3
Now holding all 4 of A,B,C,D still gives 1. (Again every combination of 4 bonuses will have the same bonus value of 3.) And then it goes on to consider every combination of 5 bonuses, 6,7...13,14, always taking into account the previous combination bonuses you will have created doing the smaller combos first.
And thats how it'd be done, I believe. Normal Territory_# and BonusLink_BonusName used throughout. The higher up you go with the number of bonuses, (so this map included 14,) the exponentially more combinations you'll have to create.
As far as I'm aware, you can't access the SVG of maps uploaded to warlight if you are not the uploader (usually the creator) of the map. I don't think there is any way (through warlight) for the uploader to give you access.
As for your map being near 5MB in size, if you don't have images in the SVG, then it could be over complex territories, but even so that is unusually large considering your map doesn't have that many territories. There probably is something else making it large. Can you send a screenshot maybe? I can't see much but if theres something obvious that's making the file large it wouldn't hurt to look.
