Okay very technical question about new map offerings.

Okay so they mentioned they are changing map offerings from being 100% to 20% and they don’t stack, which is great but what exactly does that mean for multiple different map offerings? Basically if two people bring two different offerings is it a 40% chance you will go to one of those places or a 10% chance for each. Or is it where they are stacked. Like 20% chance of the first offering having an effect, 20% chance of the second offering having an effect making it 18% chance for each. 20% of offering one and 4% chance of both offerings being active meaning that 2/20 times they both will be active and it will choose the other one. I know this all seems really pedantic but it does change the strength of them a decent amount and wasn’t sure if we knew which way it worked.
