Best practice
Reserve technical terms like "high velocity" for scientific or engineering contexts to maintain precise register.
Common error
Avoid using redundant modifiers like "very high speed fast". Since "high speed" already implies a significant rate, adding "fast" at the end creates a tautology that weakens the sentence.
