That's true, but CA EDD is pretty smart. If one reported $6610 in one week, and it doesn't look customary for the occupation, they'll come asking knowing full well that someone might be attempting to consolidate earnings earned over a longer period into a shorter one.
As to the extensions being extended, you really can't take that to the bank. As time ticked by since they came into existence, the weeks have been reduced, the trigger rates have been increased, the phaseout periods eliminated, and the work search enforced.
You should assume that there will be no letter, and that your benefits are going to shut off with weekending 12/28, and you should budget as that being your last payable week. That doesn't mean that you won't be paid after 12/28, but that will be the last week that you can file for, and receive payment for since weekly claims are always filed AFTER the week is complete.
However there may be new claim availability for you. Just because you get paid on a 1099 doesn't mean that you really were a 1099 employee. Many have appealed their monetary determinations and have been successful at getting UI benefits. Based on what I'm reading here, you had wages in the Oct to Dec 2012 and two weeks in 2013 quarter that weren't used for creating a claim, and if you get this 1099 income that might not be 1099 before Dec 31 2013, there might be a way to have a base period carved out using the traditional or alternate base period methods after Jan 2014.
