Hi,
Thanks Peter for your great explanation.

This is exactly what I get doning variable
substitution and symplification in the formula that
comes in ISO 7816-3: 1992.

Carlos,
Use the current (1997) edition of 7816-3, not the obsolete (1989) edition.
Its still not easy to do the calculations, so readers of this note should
check it over carefully.
7816-3:1997 section 8.2 on work waiting time:
wwt = 960 * WI * (Fi / f)
f = card clock frequency - let us assume
I'm not sure how to calculate this value when etu =
1/9600 s (default value when there is no PTS):
My interpretation of 7816-3 is that it should be a)
wwt = 960 * WI * F / 3571200
But I could be wrong. In particular, Cyberflex almost always requires a
longer wwt, and I usually set my own
