Yep,
A serious mistake was made.
Draw out drilling just like Tgrip.
Draw another line thru center of fingers. Draw straight with tool and extend.
Drill thumb on normal Tgrip orientation.
Turn ball to line up second line CLT. Drill fingers in regular spot on Tgrip with pitches oriented to the second line.
Exact span as before, exact thumb pitch as before. Different orientation of finger pitches.
