The whole purpose of the intake is to slow down the air from transonic/supersonic speed and compress it! Air at the first compressor face cannot be at a speed of above Mach 0.5. The ram effect of the intake at speed helps in some part to increase dynamic pressure and reduce dynamic velocity and a pitot intake (like the Jaguar) will work comfortably to about Mach 1.4. Above that speed, intake design needs to be more clever, using shockwaves produced by ramps or cones to reduce speed of air in the intake. As for too much air, rarely a problem due to the intake although the Jaguar Adours were very susceptable to surging with unstable airflow into the intake as seen in spins etc.
