That doesn't seem like a meaningful takeaway unless those first-year users are also only seeing the "classic" homepage. Most people aren't individually reviewing new-page submissions, they're voting for stuff that's already popular on the default frontpage. First-year users aren't immune to this— they're primarily voting up stuff that others already voted for. So it makes perfect sense that "classic" under this model would be a delayed version of default; indeed, one should expect that result with any randomly selected 10% of the voting userbase.
