Has anyone else noticed that sometimes it's hard to distinguish the functions someone is using because they use two functions together to simulate a third?
For example, someone may use Fe with Ti, and it's almost like Te. The Ti seems to ricochet off of the Fe, so the person ends up with an Ej function that's T but not quite Te.
Or, a person may use Ti and Ne together and then put Fe on top of it, so it looks as if it's NiFe, but the Ni is really synthesized from two other functions.
I know this may sound off the wall, but either you've observed something that looks like this, or you haven't.
