Worst case Hypothetical...and I'm sure someone can come up with worse, but, FWIW...
Cruising along at 12,500 and a Citation X descending out of the flight levels at the barber pole is pointed straight at you. Closure is something like 800 knots. Assuming he doesn't have a fish finder (not likely)...you will get your first warning a little more than 30 seconds before impact....enough time for a sip of joe from the onboard cappuccino machine before a nudge on the stick to avoid him.
Flying in the LA basin I've never missed a corporate jet that didn't see me (well, OK, maybe "never" is an overstatement...the Lears can be hard to see) ...it's the guy in a P210 or 172 that seems to always be the one to want to swap paint with me....and at max 360 knots of closure that 7 mile range is more than a full minute of warning...worst case.
Though certainly not foolproof, it's still amazing to me how applicable the Big Sky theory is....
