In uspsa a miss can be handled if your fast enough through the course.
A miss in USPSA is always devastating. It's a 10 point penalty plus 5 lost points from the alpha you failed to hit.
Suppose the stage winner's time was 15 seconds with 130 points for an 8.7 hit factor. If you perform identically except for one mike, you're down to a 7.7 hit factor or 88% of stage points. You would need to shave 1.8 seconds off to achieve a tie, and if you try to "go faster" for the rest of the stage you'll just make it worse.
