Ok, i-4 is the MINIMUM software depth. In Crafty (or Fritz, or Diep, or anything else), when it reports a depth of 12, the MINIMUM can be several plies lower due to null-move (or some other) pruning. Should we now say that Crafty is really getting 8 plies instead of 12 because of this? Well, you can if you want. It doesn't change the fact that DB's iteration depth is meaning software. Whether the number is i-4, i, or i+4 doesn't change that fact.
