Is there a definitive way to measure ejector tension? Or do you just measure the ejector spring?

You won't outvote the corruption.

Measuring the spring is a relative pita even with a jig to hold the ejector in place while you drive out the roll pin. I mean, it's not like pulling an action spring to measure free length.. The last time I had a carbine that was having intermittent ejection issues I pulled the bolt and hooked a cartridge rim on the extractor claw and levered it down flush. I could tell right away, by feel, that the spring was weaker than what I was expecting and replaced it.
I suppose you could use a trigger pull gauge using the technique above on a new spring (installed) and then check it against other bolts. Yep, not definitive by any stretch, but I've never known any other way. Perhaps the knowledge base here will enlighten us.
Flick test. Remove the BCG from the rifle. Insert the rim of an empty case under the extractor and with your finger on the mouth of the case, compress the ejector. Then, flick your finger back and let the empty go flying. It should go about ten or twelve feet.

I just use a pin punch to push the ejector into the bolt, if it feels like mush is needs to be replaced.

I little tidbit to accomplish two task with one act. After cleaning the bolt, place a drop of your favorite monkey jizz on the ejector and press the ejector in(I like to use the cam pin) 3-4 times to test the tension and get lube into the ejector pocket.
GET IN YOUR BUBBLE!
The force required to push the ejector flush to the breech face should be 9.9 pounds . . .
