that could be accurate, but it will be bike specific.
this is heavily dependent on each frame's top tube slope and bottom bracket height/drop.

With most frames these days having sloping top tubes, standover height is rarely an issue. If it is, you're buying the wrong frame size.
The two dimensions of most importance are stack and reach.

The main reason for building a bike with 650 B wheels is to be able to use wider tires. A wheel with a wide 650 B tire will be about the same diameter as a 700 C wheel with a narrow road tire. Frame size has little to do with wheel size. If frame geometry is similar, you would need the same frame size with a 700 c wheel as you would with a 650 b wheel
