is normalization a must?

[Bo T]

"Good judgement comes from experience, and experience comes from poor judgement. Not so long ago, I tried to quench fully sharpened, clay-backed, yellow-hot O1 tool steel in a bucket of icewater. I will never forget the sound it made... I'm sure Kevin C. was abruptly awoken by a disturbance in the "force" that night... oh, the suffering. "

Should of used an interrupted quench.
