I'm not understanding. Lists around here seem to be 100. Surely making this one 50 would be more arbitrary? I posted a preference with a reason for keeping it the standard length.
I get your preference and your reasoning for it (though again, you'd hear about the films either way), I just don't see why it would become null and void at 100. The sentiment only makes sense, I think, if you're actually balancing that reasoning against others.
