A sim that gets closer to perfection may be only demonstrating what a player won't be experiencing and therefore unusable.
A perfect sim may be only proving that it's a perfect sim because it's getting close to dealing every possible hand.
A player is really only going to experience a lopsided result at the best of times; so short sims may prove to be of more value for that reason. It's the extremes that a player really wants to see.
Once a sim proved it's own perfection, it's real value would be in running short sims.
