My point is that the actual value indicated is virtually meaningless. Every other engine gauge on display give me a value which i can compare against a min and max value. I don't have a hassle with the needle indication but rather the number displayed itself. That is why I suggest the EPR value should be replaced by a corrected % to be meaningful. So for example I would like to know that at FL410 the thrust set is 77% of what that engine can produce under those conditions. A number like 1.050 means zip. Surely the technology is around to display such info?
