Don Dailey answered better than i could do, yes minimax also scales.

Ah ? Why not ? what is wrong in the reasonning ?
Should i think :
" It scales in theory so it does NOT scale in practice " ?

we don"t have the same informations. For Minimax scales too, maybe the
improvement curve has a smaller slope than MC+UCT curve, but

From a pure logical point of vue
- Positive experiment are never a valid proof. They are only examples that
makes one feel his theory is right.
- Only counter example are proof that the theory is wrong.

Are you a troll ?
