Baccarat Baccarat Hold Percentages

Nobody responded at another forum , but I think it is interesting. Why do hold percentages in baccarat shift around so much?

NEVADA TABLE GAMES: HISTORICAL HOLD PERCENTAGE VARIATIONS

As an extension, why do hold percentages for other games shift around so much other than a substantial change in the rules of the game, a major breakthrough in game strategy, or....?

 

Interesting to see that there is not much interest in this topic. Hold percentages should be of high interest for every game of chance.

But is very interesting to see repeated comments from some baccarat experts that state players were much better in the past and then there were changes from the large table/ stadium table format to the modern offering format of smaller mini and midi baccarat tables coincide with a SHARP REDUCTION in the hold percentage reported for Nevada baccarat games. So if all the baccarat players were so much more kickass in the past with the traditional tables, why would there be such a result? Very interesting.
