It's sounding like either it's a soft block, not long enough block, OR if you're chasing waves, you're going in the direction of the waves, instead of across them.

If you're not able to have the block sit on top of two high points, and not touch the low point between them, you'll never get it flat.

Looks like you were right on the T pattern! I did that and it's finally fixed! Thanks a bunch.
