Does the metric you’re using (fraction of visitors staying at least N seconds?) actually measure what you care about? (A few possible confounding factors, off the top of my head: visitors may be intrigued by the weird colours and stay around while they try to work out what it is, but this doesn’t indicate that they got any actual value from the page content; if the Beeline thing works, visitors may find the one bit of information they’re looking for faster and then leave; if it’s just annoying, annoyance may show up in reduced repeat visits rather than likelihood of disappearing quickly.)
I think it’s a reasonable metric. It’s not perfect (I’d rather measure average time on page, not a cutoff), but I don’t know how to do any better: I am neither a Javascript programmer nor a Google Analytics expert.
