2017 has been good, dare I say it. Better sector pairings, more crew (allowing for more 2 sector duties) and slightly longer turns have greatly improved the schedule vs the previous year. Rolling totals are between 750-800 for me but undoubtedly you will find people with more or less than that. A few blocks during the summer got pretty disrupted but were in response to big slot delays affecting duties at the start of the block - not necessarily caused by anything within the company's control.
