Hi,

About Gold Upgrade,

The statics for gold upgrade depend to:
Ammo -- Armor are linked
Attack -- Speed are linked
Range -- Scan are linked
Shots (alone)
Hits (alone?)

So the function how give the value of gold upgrade is not so easy to find, it depend of many parameter.

There is another parameter: See the RANGE upgraded
- if the unit have low RANGE, [like Infantry] the upgrade will be +1 per upgrade.
- if the unit have high RANGE, [like scanner] the upgrade will be +2 per upgrade.

I have the following result :

FOR RANGE upgraded:
+1 per upgrade:
3-> 61 - 299
4-> 34-125-364
5-> 23-68-172-386-791
6-> 17-44-98-201-386-694
7-> no example
8-> no example
9-> 9-19-33-57-93-149-230-345-505

+2 per upgrade:
10 -> 23-68-172-386-791
11-> no example
12-> 17-44-98-201-386-694

I have found that to DOUBLE the attribute, you must pay at all a multiple of 720 gold.
For SHOTS:
1 -> 720 (you double)
2 -> 79 - 641 so to upgrade from 2 to 4 you must pay 79+641 = 720 gold... not a coincidence.

For range:
5--> 23-68-172-386-791 so to upgrade from 5 to 10 you must pay 23+68+172+386+791 = 1440 gold.
6-> 17-44-98-201-386-694 so to upgrade from 6 to 12 you must pay: 17+44+98+201+386+694=1440 gold too, not a coincidence.

I can explain you why you cannot upgrade 3 range unit more than 5: because
to go from 3 to 6 you must pay 1440.
or we have 3-> 61-299 to go from 3 to 5 we must pay 61+299=360 gold.
from 5 to 6 we must pay : 1440-360= 1080 or because 1080>800 we cannot upgrade to 6 a unit that have 3 RANGE.

So the original upgrade function have a human imposed limitation: not to pay more than 800. (you have already say that)
I can find this function but ... with time.
