The SPPP invoked a wide range of names to define the events of November 21 for readers.
On the second day of coverage the SPPP chose a much more inflammatory term: "rampage.
On November 25 the SPPP used the term "tragedy" for the first and last time.
Thus within the first nine days of coverage (November 22 through November 30) the SPPP had constructed a contradictory vocabulary to define for readers "what happened?
The SPPP chose a word that would horrify readers given how massacre had been previously used.
In the preceding one year (November 22, 2003, through November 21, 2004) the SPPP had used the word massacre in headlines only three times.
The 100 SPPP average yields for RRPS Cycles 0, 9, and 18 of Population A and Cycles 0, 5, and 10 for Population B in Table 1 show how the single year SPPP tests can be combined to add weight to population cycle relationships when the same populations are included as checks in the SPPP tests for several years.
With essentially no competition in the SPPP tests, the SPY of the average plant in the 100-plant A population had increased more than five times in response to 22 cycles of RRPS.
The 1-yr SPPP tests can be combined to add weight to the effect of RRPS on the SPYs when various cycles of Populations A and B are included as checks in the same SPPP test for several years.
Classification of the yields of the individuals in a 100plant SPPP test reveals the existence of plants yielding much more than the heaviest plants in the base population.
The SPPP test precisely measures the average effect of the increase in number of yield genes in 100 plants.
