the Canadians had 294 minutes with QSOs – 535 QSOs at a rate of 1,82 
QSOs per minute and the Americans had 210 minutes with QSOs – 322 QSOs 
at a rate of 1.53 QSOs per minute."

So we have a rate of 109 Q/H for PT5M and 91,8 for PT5C. Difference is 17,4.

I've re-read http://www.ncjweb.com/howmuchisadb.pdf
On page 9, it gives a formula of delta-rate=b*dB/10.

In the article (OF COURSE, this is not the same contest etc etc) for 
south america b is 47,95. So the equation would give a difference of 
3,62 dB. Not too far from what HFTA gave you...
