Idols stacking

Hello i have a question regarding the %increased chance for idols. I will use the heist for example because i want to know if the chance can stack above 100% and if yes what is the upper limit for it. Some heist idols have "increased chance to drop blueprints" and others have "increased chance to be deception,egineering,agility". If i stack any of these past 100% will it matter? Or is the 100% the upper limit? I would love to use some map idols for connected maps for my heist setup and the %increased chance modifiers are the only ones that i can drop if the chance does not go past 100%

Each random event in this game have a chance (b%) to happen. There are two ways to increase it:
1. Add +#% to chance of this event (flat chance)
2. Increase this chance by #% (increased chance bonuses)

The total chance will be (b + f) * (100 + i) / 100 precent (here f is sum of flat bonuses and i is sum of increased bonuses)

Total result caps at 100% which means event always happen.

Answer is following: you can get more than 100% increased chance and that will work. However, if you already have 100% chance for event to happen, adding more bonuses to it will have no effect.

Thank you very much for all the information!
