Worst penetration ever ? (cross-posted)

I wandered into Trump Plaza in Atlantic City.
I was in search of $25 Six Deck tables.
There were several tables with $25 minimums and $1,000 maximums.

What I found was all tables cutting off 2.5 decks.

Has anyone ever seen a shoe game with penetration worse than 58.3% ?

I know that I haven't.
