To me it just reinforced the curiosity of why so many domestic competitions play 4 days instead of 5. I'm not really up with the history of it all, apparently 1988 it swapped from 3 days to mostly 3 days with some 4 day games, then all 4-dayers in 1993.
Yes the south group got almost all results, but what good is it having no scores above 200 and Darren Stevens being unplayable? The final was a far better emulation of Test cricket. You had a good pitch, quality players getting hundreds and bowlers having to work for their wickets. If it had been 4 days it would have been a nonevent. You always hear about wanting more express pace & spinners in the game, well 5 days with fewer overs per day does that. Other than obviously having to play about 15% fewer games with 5 day matches, I see a lot of positives and very few negatives.
