I would be careful to point out that hard numbers were deliberately NOT discussed. Though some general things were thrown out, they were not extensively discussed nor agreed to. I personally think 2-4 is "in range", though 8 maybe not so much. Of course it depends on exactly how the non-blocksize limit accounting/adjusting is done. Still, the "greatest common denominator" agreement did not seem to be agreeing to an increase which continues over time, but which instead limits itself to a set, smooth increase for X time and then requires a second hardfork if there is agreement on a need for more blocksize at that point. > - Hard fork method: Leaning towards "if (timestamp > X)" flag day hard > fork Y months in the future.
