NiMH and NiCd do have very similar discharge curves for comparable "C" discharge rates. (If you discharge a NiCd at a rate that will discharge it in three hours (to pick a rate), the discharge curve will look very similar to a NiMH being discharged at a rate that will discharge it in three hours. The differences you do see will mostly come from different internal resistances.)
some rare or non-relevant circumstances
What are you talking about? I'm talking about NiMH discharge curves, all of them, not some "rare or non-relevant circumstance".
I'm sorry that you got your information from an incorrect web page, but you did -- NiMH cells start at 1.41 volts, not 1.22 volts, and the discharge curve you explicitly linked to does not represent reality.
This demonstrates a lack of common-sense on your part, nothing else.
Again, I'm sorry that you got some bad information, but you did, and I've shown it to be bad with many different sources.
What would show a "lack of common sense" would be a failure to acknowledge that you repeated some incorrect information, learn from that, correct it, and move on.
