Yes, there's an invisible R for upgrades. Used to be X when "F" was full-fare two-cabin first.
It makes sense that you'd get the upgrade. In my experience, it's very often the case that if C>0 & you're within the upgrade window, then R>0. I will say that closer in, say within 24 hours of departure, I'll see C availability (say, J2C1) when it doesn't seem plausible that I'll clear the upgrade. In those cases, if it's a long enough flight, I may set a reminder for myself to check the upgrade list 4 hours out, and burn a BXP1 for a C seat if it looks like I won't clear.
