Another thing I'd bet is, Canon only accounts for new lenses other than the kit bought. I am quite certain that more than 5% of DSLR buyers also buy other lenses, but I think there is a very significant market for used lenses. I'd be willing to bet that at least 30% of Canon DSLR owners buy another lens, and the majority of them buy one used.
And even if your average enthusiast has lets say 5 or 6 lenses, the same person will also buy multiple bodies over time while the lenses are used over a longer timeframe. That dillutes the ratio towards that 1.5 lenses per body.
Then one should factor 3rd party lenses in; how would Canon account for lets say a 5D3 with Tamrons 24-70/70-200 and Sigmas f/1.4 primes? A quite reasonable setup that looks like an expensive doorstopper from the isolated sales/registration numbers.
