Peter,
I think there are a lot of truths within the reponses you have to your question, esp. from Brendan and Astro744.
The magnification though is what is perceived by the eye compared to what is recorded by the camera. If the image size on the film/CCD plane is the same as your eye perceives it, then you have 1:1. But when you take your pic and display it on a sheet of A4 paper and it fill the sheet, you have 'n' times that amount.
Mathematically though, your mags are f.l. of scope divided by the f.l. of your camera lens when set to 1:1. A value of 70 for the latter seems a bit high to me. I did the test on my Olympus E-620 and got 50mm, which I'm happy with. The value you got suggests a larger format camera! However, when all is said and done, it is all very subjective.
Hope I haven't confused the issue too greatly.
Robert
