First set your timing as ockham suggests.   If you have 47 poses that are to be evenly distributed across the range of 230 frames.

230 divided by 47 = 2.89

So:
Make your animation 235 frames long (47 x 5).

Go to frame 1:  set the first pose and set a key.

Advance 5 frames, set the next key, and so on until you set them all.
