Edam states the case well.
I would only add to that with - please wait until your attitude (which means Pitch) correction brings your IAS Up or Down and then stabalizes - and THEN Trim for straight and level.
If you try and trim whilst the aircraft’s speed is (dynamically) increasing or decreasing - then you’re trying to hit a moving target.
That works for the C150 right up to the 747.
Let the aircraft forces change - stabalize - then Trim it up.
Let us know how you get on. Sometimes Piloting is Waiting for the airframe to catch up with our will.
That’s called being ahead of the Aircraft.
