High Salery No Advantage ?

This is two oil companies from one of my countries. Then I raised salery from 300 to 500 for Oil company 2, I expected an increase in oil production, but nothing happend?

Oil company 1:
Salery at 300 / production at 123% = 2,291,667 tons

Oil company 2:
Salery at 500 / production at 130% = 2,291,667 tons

Maybe its just me again missing some vital information in the documentation, but why dont produce more, why this rule?

Check your transaction logs. Check view recent sales in both corporations.

My air transport corporation in one country has 114% production and sells around 2,228,970 units per month.

My air transport in another country has 125% production and sells around 2,425,000 units per month. It is producing more don't look at estimated production.

Oh yeah, I was looking at "Maximum Production Capacity Per Month" and "Estimated Production This Month", not recent sales, which show they produce a lot more, thx

Oil company 1:
Salery 300 / production 123%

Estimated production: 2,291,667 tons

Recent sales:

Jun 03 3745 2,812,196 tons
May 04 3745 2,812,196 tons

Oil company 2:
Salery 500 / production 130%

Estimated production: 2,291,667 tons

Recent sales:
Jul 03 3745 2,693,770 tons

Everything seem to be OK

Increasing salaries to a level of 300 (3 x base salary), is profitable.
above 300 it can be good in some cases but not always.
it also depends on the upgrade level of the corporation and the market situation.
