Same here. I had a look at 100's of pages, and used all kind of
search-terms, but nobody goves any hard figures. So for now, just for the
heck of it, let's stick to Paul's calculated 666 hours. But let's make that
a worst case figure.

I would say that the chance of a non-recovereable error happening on the
same spot multiple times over dub after dub, is very small. So I see no
accumulation there. The only thing which accumulates is changing of the
bits over the whole tape, making it different from where it started with.
But as wel all agree, nobody notices these small losses. And you would only
notice them when comparing to the original again.
