Put another way - does the counter get better or worse with the new card? I realize that an A will do some things with B firmware, that’s not the question I’m asking. I’m looking for A to A or B to B timing data.

Yes. I made some measurements with the previous microcontroller-based board (48 MHz sam7x) versus the stock CPU card. I have not yet had a chance to repeat that exercise with the current board. Look at the 23-Jul-2011 entry on <www.jks.com/5370/5370.html> Very much dependent on what the measurement is, but a range of 5-72% faster.
