You don't actually need *any* standover height to ride a road bike on the
road, but a little is usually considered desirable by most people. If you
can straddle it with both feet on the ground, you've got enough. When you
say the builder missed it by 3/4 of an inch, that's implying a precision
formula in these matters which really does not exist. Any custom frame is
going to compromise something in order to achieve something else, otherwise,
you could just get a standard production frame. I have a custom-built
made-to-measure frame, and, with 25mm tires on it, I can just straddle it in
bare feet, and with my riding shoes on, I have about an inch of clearance,
which I think is ideal. If you're concerned a mistake was made, ask the guy
who is responsible for designing your frame.
