hear what you're saying, but presumably somewhere between a 30 degree wing drop and the nose pointing vertically down, there's a threshold where it doesn't make sense any more to add power.
Yes, I see what you mean. Once the situation has developed to that extent, the unusual attitude is one with a high, or rapidly increasing airspeed, and you are right, in that situation, to reduce power.

Is this happening as a result of your rudder input, ie. does the wing drop, then you apply opposite rudder, then the aircraft rolls over the other way?

In that case you are being too heavy footed, and applying the rudder too soon, before you have unstalled the wing.

If the same wing continues to drop after you apply the rudder, then you have not unstalled the wing first.

Remember the first thing you must do, before anything else, is move the control column forward far enough to eliminate the stall symptoms!

The PA38 is particularly inclined to drop a wing at the stall, and as a result of experience it was recomended that manoeuvers involving an approach to the stall in the PA38 not be started below 4,000' agl as an added precaution.
