Having had to fly the EPR gauges for years, I can only say they suck.
You'll try to be adjusting those little numberswhen on the approach, and your eyes should not have to rest for longer on the engine instruments.
If I remember correctly, EPR 1.05 was ok initially on the 330, but I don't recall if it was the 200 or 300.
I actually adjusted thrust with the speed trend vector, trying to keep it zero when on speed. Just don't be chasing it too much.
Or have the A/T engeged until established on glide with Flaps 2 and note what it will give you, and use that as reference for the future.
