What do you mean elaborate? I don't see how anything I said was hard to understand. If we find x or t from the na cell, we've found the x or t from the prime solution cell. That means, if we're meant to find x or t, the na cell is irrelevant. Which means there's something weird going on.
Considering it didn't come up in my post, I wouldn't have a clue.
Thanks anon. Are you one of the namefags posting without your name?
