Base chance for extra content.

Hello,

so in the past it was always assumed that there is a base chance for extra content to appear in a map. It was assumed that by default, most sources of Extra Content appear at a base chance of approximately >8% in maps.

Now my question:

Since we do have the possibility now to make i.e. Breaches appear with a 100% chance, can I (assuming base chance with >8% is correct) just spec into 92% chance for Breaches to appear in my maps and assume that every map from now on will have a Breach in it?

I would be very great-full if a GGG employee could chime in here and and answer my question real fast with a straight "yes" or "no".

Thanks much in advance!
