Obviously loads play into this - loads in E+ and Z availability are good helpers in making a choice, particularly if you're within a couple weeks of departure.
How many times have you not cleared while on a B fare? In the flight that I was on, 1ks with Y fares did not clear either....
I think this rapidly becomes a race to the top - if everyone buys higher classes of fares, your relative position stays the same but you have paid a lot more than necessary...
