Though charts that say "double for as little as possible" leave a small hole. Ideally you double for an amount so insignificant that really you're just taking a card face down for free, right? What would be neat to see is the critical fractions for those doubles; that is to say, the percentage increase required for the double where the EV of doubling is equal to the EV of the best non-doubling decision. If you saw a purple "0.25" in the cell, for example, you'd double for less if you could put up a quarter of your original bet or less; otherwise you'd take the action in the you-can't-double-for-less chart. (Alternatively, show the reciprocal of this fraction. This requires simpler math at the table since typically the double amount is something like a dollar. If you see a purple "20", double if your bet is \$20 or more.)

Not that such a chart would ever be useful, of course, since this game probably doesn't exist :-P

Another chart your idea would be useful on (and I do know of real casinos where this would be applicable) is the one for the strategy when you are allowed to double, but not hit, after splitting aces (for the cases that a full double is not appropriate but a double-for-less would be if low enough in relation to your original bet).
