Yup. I've not seen higher than 94%. I only have 2 teams ATM, but both are 20 and 19. Saving up funds to get another team, but I want more gear to increase gold success rates.
I suspect that the + effectivness does not apply the success percentage, but is instead a "bonus" to what ever formula is used to calculate the chances.
And then there are the strike team traits you earn for mission fail/success,. Good ol' fashion RNG.
... sgh
With quick response vehicle IV (150 MF) and a level 20 team with 5 positive traits, I have a 84% chance of completing gold hostage situations, if that helps
