I am thinking they are definitely losing ground. If every Monday takes 5 + business days, they will be at 60 to 90 days easily.Here it is a Thursday and they are still approving applications that were accepted on a Monday 7/18. I suspect that Monday 7/25 was also a big day for accepted but before they can start to work on those they still have four days of accepted permits to process. It looks like they are just getting deeper into the hole and approval times will keep lengthening.
Keep an eye on when they start clearing and finish clearing the Monday (biggest day's) accepted applications and you will know weather they are gaining or losing ground.
