A 0.2% increasre in the first quarter, a 0.1% increase in the second then the two drops would, in bad maths, be a 1.8% drop.
There's a similar graph across two pages of today's Guardian but it goes back to 1970. It's easy to see that the last section, since September 92 'Black Wednesday' has been atypical, with continuos blue bars. Before that the red bars occurred quite often, particularly from 70 to 84.
There should have been a mild recession in late 2001 but it was deemed politicaly unacceptable (sept 11).
The recession was "prevented" (simply put off) by Bubbles Greenspan.
The problems the 2001 recession would have solved continued to build, until 2005, when there should have been another, but again, central banks bailed out their political masters.
Not only were inefficient companies saved the success bar was lowered so much that private equity madness like the boots buyout became profitable.
Until the next "snag", in 2007.
Central banks were unable to perform their "miracle" of "saving" the day, so now we get three (possibly 4, dont know enough about '95) recessions all rolled into one combined with the sort of madness that was allowed by the earlier rescue attempts.
