I said you make one overlord because the other died.
If it wasn't scouting, I can say it is a cost due to scouting if it was caused by the scouting.
Have you read my posts? I have shown you evidenece as to why the second overlord is built. Building the second overlord is just a COINCIDENCE of the first overlord scout/sac. The scouting has been achieved, there is no need to build that second overlord. You build it cause you want to build more units not due to scouting, the scouting has already achieved. Think of it as you are hungry, it requires 1 apple to be consumed to fix your anger but you actually indeed consume two apples. The ACTUAL Cost due to hunger is still 1 apple, there was no need to consume the second apple. The mere fact that you consumed both does not mean you can attribute costs of both to hunger. It is a coincidence that you consumed that apple when you were hungry, the costs and resources spent for/due to hunger is still one apple, the resources spent on second apple is just for you own satisfaction and merely a coincidence.
Since you thread is A MATHS PROBLEM. I will use some mathematics to solve you problem.
1 overlord = 100 minerals = +8 supply
Scouting/overlord sac = -8 supply = -100 mineral
The result of an overlord sac is -100 minerals therefore scouting cost/spent is 100 minerals.
The above conclusion can be further proven further down the road.
2 overlords = 200 minerals = +16 supply
1 overlord sac/scout = -100 minerals = -8 supply
total minerals spent/cost (200 minerals) - scouting/sac = 8 supply (you have 8 supply remaining after scout/sac
As we know 8 supply costs 100 minerals therefore
Scouitng = 200 - 100
= 100 minerals
Minerals spent and cost of scouting is 100 minerals.
The maths above proves my statement that only 100 minerals is spent due to/because of scouting/sac. The second 100 minerals spent is due to /because you want to build more units/supply. There is NO NEED to build a second overlord for scouting or because of scouting, scouting is achieved, there is NO NEED FOR A SECOND OVERLORD.
