Pestilence and Replacement Levels

[RedAss]

Here's the situation:

When the variablevalue is 1, it triggers a pestilence level of 1, which as I understand it means roughly 1% of equipment will be lost (give or take some variables).
Now, when the variable value is 2, I want to trigger an event that sets the pestilence level at approximately 2%.

The question is, do I set the pestilence level at 2, because that is the level I want?
Or does the second event take into account the first event, making the effect cumulative, in which case I would put the level at 1 for the second event as well, achieving a little more than 2%?

Similarly with replacement value:
Say Event 1 sets the value of replacements for a force at 90%.
For Event 2,I want to reduce the replacement value by roughly another 10%.

Should Event 2 set the value at 80%, because that is the level desired?
Or should Event 2 be set at 90% again, because it will be 90% of the original 90% reduction?

If you set replacements to 90%, any later set value will use that 90% as the base.

My opinion on the Pestilence setting is that it is static. So a setting of 1 followed by a setting of 2 will not make it 3, it will be 2.

That's what I needed to know, thank you kindly!
