Last season i filled in for a mates side . 40 overs per side . If you didn't bowl the overs in time the innings stopped at the designated time regardless (ie meant to finish by 3pm but only 35overs bowled ,then the innings finishes at 3pm / 35 overs etc . In this example the team batting second only has 35 overs to bat ,instead of 40, which is where the time is caught up . Apparently, the thinking is that the penalty for the first teams slow over rate is that they are docked the overs they didn't bowl , but the team batting first is deprived of knowing when their innings would end /how to pace their innings . Even so , i understand the logic behind this , but personally, i prefer proper /80 over/full day innings , so 40 overs felt like a rip off , 35 etc just felt a bit 'mickey mouse' for my liking.
