The former.

Each dit or dah implies a following dit interval - this in addition to 
the 2 dit intervals following a character - and this in addition to the 
user chosen number of dit intervals following a word (used to be fixed 
at 4).

This is why 4 dit intervals between words worked so well - it already 
implied an additional dit interval after the last dit or dah in the 
word plus 2 dit intervals after the last character in the word which 
would really translate into a grand total of 7 dit intervals after the 
last key up in the word.

We send the dit interval following the second dit in 'I' plus the 2 dit 
intervals between the two characters which totals 3 dit intervals 
between "I" and "S".

Have a listen - the free demo will generate CW with a variety of 
hardware/software keying options so it shouldn't be too difficult to 
set up with your particular rig/interface.

So do I, but my customers have come to expect that the theory actually 
gets turned into something that they can use :)
