No, not more than I wanted to know.  It is very refreshing when every once
in awhile someone asks an intelligent question and gets an intelligent

I've come to the conclusion, based upon the consensus of opinion of others
besides yourself who have contributed to this discussion, that
the answer is basically improved techniology that allows the cassettes
to be recorded at 1 7/8 ips versus the formerly superior 7 1/2 ips that
was recommended for reel-to-reel tapes

Of course, as I mentioned a little earlier, had they attempted to record
cassettes at 7 1/2 ips, you'd be lucky if you could get more than 10 minutes
of music on each side so it would have been highly impractical
to have done so.
