You're completely wrong in the number of lashes.

Old testament law limited it to 40 but Jesus wasn't punished under biblical authority, he was lashed under Roman authority which had no such limit.

A Roman flagrum was used which had multiple whips with balls at the end of it.

By studying the shroud of Turin Estimated Number of Lashes:

About 90 to 120 distinct scourge marks are visible on the body

Because each blow from a Roman whip (called a flagrum) often left multiple marks (typically 2 or 3 from weighted tips), researchers estimate:

There were At least 40 to 60 actual blows all over his body, each one leaving multiple lashes.
