Cantor (M Resort, Tropicana, Hard Rock, Cosmopolitan) was giving 5% of coin in on their interactive (E-Deck) VP, blackjack, and other electronic table games back in cash sports wagers for a while. That was a huge edge on a paytable that was approximately 98%. So, I learned how to play perfect strategy VP real fast. You might be surprised at some of the plays that you can find from even the "sharper" places.
They recently cut it down to 2% and dialed back the paytables on VP. The floor supervisor told me it was because they "realized that they were getting killed." I was just thinking, "Well. No shit." Then, he said they might bring it back eventually.
Worth checking into every now and then at least.
