Sounds like someone at CA missed the lecture on conditional probability.

The probability of two spies with a 75% chance of opening the gate woould be:

p(spy one succeeds) + p(spy two succeeds: given spy one failed)

this would be (75%) + (75%)*(25%) = 93.75%

Add a third spy with a 75% chance and it's:

75% + (75%*25%)+(75%*6.25) = 98.43%

You can never get all the way to 100%.
Ever seen public order over 100%? Yes, you have. You have to play by the rules of the game, not the rules of the physical world, because, well, this is not a physical thing. If you look at the mechanics for things, you'll notice that most things give things in batches of 5%. For example, the amount of unrest in a city caused by spies, is skill level of the spy multiplied by that 5%. So, it would seem logical too me that this logic in carried over to this section of the game too, and then you'll easily get over 100%...
