Please review this potty schedule!

Long post, sorry! Please critique my potty training schedule! A little background first:
When I got Bentley he was 7 months old and about 85% potty trained from his previous owner (only going #2 in the house about once per week). After I brought him to our home he was doing wonderful, only a couple of #2 accidents and it was my fault for not yet knowing his schedule and signals. Never peed in the house at all. He has been crated during the day while I am at work. I come home for lunch and let him out then he goes back in the crate until my husband gets home from work at about 4:30. He sleeps in our bed at night and I usually take him out once in the middle of the night…around 2:30 or 3:00am. Sometimes if he would get antsy I would put him off the bed and he would get free roam of the house. He would usually run around playing with a toy for a few minutes and then end up curled up on a pillow next to my bed on the floor and would sleep til the alarm goes off at 6:00am. No accidents during the night ever. He had not been using the bathroom in his crate at all. Or having any #2 accidents after I learned his schedule. This past week it seems he has been regressing. Some time during the night he peed on the rug in my living room. He also went poop in his crate while I was getting dressed for work this morning. He also peed in his crate three times in the past week in his crate while I was at work. That’s 5 accidents in one week (that I know of) when I have had him for 2 months now and he had not been having any accidents. I’m not sure why he is regressing. Maybe he is getting to comfortable since I have had no reason to punish him at all so now he thinks he can do as he pleases? I am unsure as to what his little mind is thinking. Anyone have any ideas?
Also I made a new schedule that I will be starting today. Please feel free to let me know if you see any issues or anything wrong with it. I know it’s a lot of time in the crate, but this is only temporary until I feel he is on schedule again, then he will slowly graduate to more time out of the crate. He is 9 months old now.
