No, that's actually an approximation of the value derived from my secret black box which was smuggled out of Nazi Germany and resurfaced during the Cold War, and subsequently came into my hands through a chance encounter at a car boot sale. (It's a bit like that Enigma machine that was discovered in a garden shed recently and sold for a tenner). After suitable calibration and back-testing it now produces results to 9 decimal places but I feel it would be insulting the intelligence of fellow competitors to go that far.
