The twist rate is much larger than an inch, no?

No.

In ethernet/Cat5 cable, the twist rate is several, full twists PER inch.
Someone more familiar with LAN cable probably knows the rate.

I wouldn't think a problem with the twist in the last
inch wouldn't matter much.

It would. ...and apparently does.

I have spoken with several techs in recent years that claim it is CRITICAL to
CONTINUE the twist ALL THE WAY to as "flush with/against" the connector as
possible.
