Useless info or guide to efficiency?

Webman's recent posting of a fun fact caused me to think of another. What percentage of dealt cards are kept when making the proper strategic choice? Of course the answer depends on the game.With 9/6 Jacks or Better, the answer is 41.6701% (if you hold 4 when dealt quads; a slightly higher percentage if you hold 5). You hold 5,414,952 of the 5 x 2,598,960 = 12,994,880 cards that can be dealt, summing over all the possible combinations.With Full Pay Deuces Wild, you have nearly 2 1/2 times as many hands where you hold all 5, but almost 5 times as many hands when you toss all of them. Overall, you hold 38.5997% of the cards that are dealt, 7.36% fewer held cards than 9/6 Jacks or Better [(41.6701 - 38.5997)/41.6701].

Bob Dancer in the Special Feature video in VPFW says that Deuces Wild is, in his opinion, the most fun game; and that, if he has a choice to play 2 games that are otherwise equal in value, he will select Deuces Wild every time.After thinking about this, I wonder if he is making this choice for efficiency: to save himself 7% of the work necessary in pushing the hold buttons.Edit: When compiling these numbers, I did not consider that the 4 dealt royal flush hands would be autoheld, but I suppose that could modify the hold percentages slighlty!
