Oh, on average my people are about 95% accurate. Give or take five percent. That said, we only see the future as it is at that moment. The slightest change can alter it entirely, which makes things... less so.

For instance. I have a vision that Grif will rob the snack machines again. I mention it to someone and they decide to grab the snacks they like first. He can't steal those items, so the future has changed.

In a more dramatic example, I've seen several of you die on various missions. Well, a general 'you'. Legionnaires. If I'd seen you die, someone would warn you. Anyway, I'd go in and whisper a word into Jazmin's ear or just alter the duty roster myself and, well. Things have turned out better. For the most part.

The thing is, most of the time when we mention a vision, people automatically seek to either change it or ensure it happens. They go into a situation more recklessly or more cautiously than they normally would, which means they're not acting the same as they were in the original future, which means that a new one overwrites it. This gives my people a reputation of being less accurate than we actually are.
