Install a Pyro and an oil temp gauge into the truck and you can ball-park weather or not the engine is in the right injection timing ranges or not.

I understand what you're saying but I don't understand how to quantify it. Setting the timing with the timing jig compares the push rod travel with the piston travel

The measurement for injection timing is in thousands of an inch compared to a set point in the piston travel. There may be a way to convert that into degrees but I'm not smart enough to figure that out
