Minecraft FPS Optifine question?

If you press "F3" normally in Minecraft you can see the current FPS at the top left, for example 85 fps.

But if you do that with Optifine, there are 2 FPS values, what exactly do they mean? Eg 107/65

The current FPS are on the left. On the right are the lowest FPS that occurred during the session.

Ok thanks, I thought something like that, but I wasn't quite sure ^^
