Will you be using an Action Replay?

Bleh, that post was from hours ago... where to start...
Well, short answer is no, not quite. Using your example:
B / 21 / 25 / B / 31 / B
Step #1 would be to figure out what those Bs are, because inheritance shifts around with each frame (advanced by all the RMNPCs outside), but the "underlying IVs" ("base egg IVs", that 21, 25, and 31 and what's "underneath" the Bs) do not (for the first egg, as long as you don't walk much, or withdraw any pokemon from the PC). What determines if you've found a good seed, or a bad seed, is what the "base egg IVs" are, because if your "base egg IVs" are good, it matters less what inheritance you happen to get.
An example from my use:
I spent like 8 days resetting on 30-40 different arbitrary seconds to see what seeds I commonly got on those Date/Times. I then ran those seeds through the Researcher in the RNG Reporter to generate a rediculously long list of "IV frames". Base Egg IVs are on frames 8-13 (in order) for the first egg (as long as you don't walk much, or withdraw any mons from the PC). Here's just one arbitrary result:
MTIVRNG Seed: 9757ecef
IV Frames: 8-13
Base Egg IVS: 30 / 26 / 30 / 28 / 25 / 31
This is a quick, easy, consistent seed I happened to stumble upon that gives 2 30s and a 31. Now, the RMNPCs all screw around with your inheritance, but you can "usually" have a little say in that if you use power items. At this point, our understanding of power items "seems" to be that they have a 50% chance of jumping to the next PID/Inheritance (they seem to be tied) Frame that fits the Power Item. So, when I want babies that are:
30 / X / 30 / A / A / 31
I put a flawless ditto (or a flawless RNG Capture) in the daycare with either a SAtk or SDef Power Item and a parent with an everstone with the proper nature. I then start resetting on that seed (Date/Time) and varying the time before I pick up the egg (watching the spinning mons as a guage, or using a stopwatch). After a few resets, I usually stumble across an amount of seconds before picking up the egg that gives the inherited IVs necissary for my wants. Most of the time the PID is what I want too, because of the everstone, but when it isn't, I just have to keep checking different amounts of time before picking up the egg until I DO get what I want. You can also switch the power item to something different, and will usually "sway" the egg inheritance/PID toward something else, that can be useful if you're not seeing the result you want.
Now. That's the "basic" way to do it. But you can get unbelievably better results (like 830c3ab4 (F 1948-1953).......30 / 08 / 31 / 31 / 30 / 31) if you look further up the IV frame list. But that's for another day. :3
