2.5% annual growth plus a 3.6% upward statistical revision should result in this year's GDP being about 6.2% larger than last year.
Nope.
The US will grow by about 1.5-1.7% in 2013, down from 2.8% in 2012.
GDP growth compared with the previous year's quarters were:
Q1 2013 vs. Q1 2012: +1.3%
Q2 2013 vs. Q2 2012: +1.6%
Q3 2013 vs. Q3 2012: +1.6%
Table 7 & 8 below:

The US GDP didn't even grow by more than 6% in the favourable end-90s ... (look at table 7)
