That's a core mechanic in games like Dispatch.

People don't like seeing a 95% chance of winning and then losing. The game tweaks the odds, so certain thresholds become gimmes (something like "if the displayed odds are better than 75%, treat them as 100%").

That's stupid. That would piss me off.

Fire Emblem does something complex with averaging random numbers to do the same thing - a 95% chance to hit becomes 99.5, and the reverse for low percentages.

Conversely weather forecasters report a 40% chance of rain when the actual chance is 10% or similar.

So I have a bit of sympathy for people who don't have a good intuition for probabilities, given that the world is constantly gaslighting them.
