Re: 30% chance of failure?
I seem to recall some games were terrible because they used "turbo loaders" (increased baud rate) and entirely didn't bother with error correction, so even the original cassette was hard to load.
Using a Multiface One to deal with - (ahem) - creating backup copies, worked much more reliably because it just dumped the RAM image out.
