Base chance to encounter Content (Master) / >100% chance

The wiki no longer lists a base chance to encounter a master in a map, and I wwould like to know if anyone has data on what that chance is.
I assume it is >0%, since I have zero Einhar nodes and I have encountered him.
I ask because I want to know if I can save on nodes which give me a chance to encounter a master.
Currently, for example, I have 104% chance to spawn Niko. I want to know if and what the base chance is, so that I can remove redundancies.
I am not sure if the same is true for non-master content. I would like to remove redundancies from Expedition and Harvest too, but things are complicated with the "block" nodes.
Taking "dimensional barrier", for instance, plus 4 other nodes which block content -- is this +x% chance to encounter this "other" blockable content then modified somehow or does this remain base?
thanks in advance

With the new patch I (think) the base is 24%?

Is there any data on this anywhere to confirm?
24% for masters, or all content?

Where did you get this from?

I can confirm that it cannot be 24%.
I respecced into +80% Niko and ran maps until I got no Niko mission. It only took about 9 maps, but there was one which was did not have Niko. If it were 24%, then I would have had 104%.
So it must be 19% or lower. I will try to continue testing, but I can only do it in 8% intervals.

wild master chance was 2% per Bex_GGG

Unsure are there any nerf or buff anyway

Also, Ruthless master chance is different

Not sure where you are getting this from either. Can you link your source?

There's a 10% chance to spawn naturally spawn a master - a 2% chance per master.

Since Zana is removed from the game. Unsure it has changed or not. As the wild master used to be like that

The way this system works is that if you are running a map where you have not force-spawned a master through an Atlas mission, then you'll have a 10% chance to spawn a master naturally. The system will roll for a chance of whether or not there is a master and then roll again for which of the five masters you would get.

And since this patch changed again to make master are no longer mutually exclusive, either it still keep the 2%ish chance or ninja changed.

Sorry, meant 2%.
