A single lowest framerate should not be recorded in the database, because of 2 reasons.
1 - It only depends of what scenes has been selected on a short ~5mn video: compared to a ~10 hours game the sampling is really too small.
2 - There are some games that use a half framerate during cutscene or slow motion scenes, for instance if you say that the last COD has 30fps as its lowest framerate (during slow motion, cinematics scenes), it's not at all representative of the whole game. Later, people consulting the database could think the game constantly hovers between 30fps and 60fps.
And what about Forza 5 with some real-time scenes running at 30fps?
Instead for Ryse we could say the game may hovers at ~20fps during sustained moments like:
- Occasionnal sustained (5 seconds) framerate : ~20fps

That's a really cool site with a *lot* of data! Hard to beat that. But I'll add the options they record though, who knows one day consolidation will happen.
