Personally, my report slip was a work of fiction for the last 5 years. They'd give me a hard time if i reported less than 8 hours a month so i decided to just f**k it and put 10 hours a month and random mags/books/studies. They stopped bothering me then.
Yes, a blank report slip was my canvas. My ex-wife never put in her report slip, she always forgot so i did it for her. Again, it was all fiction.
One time the secretary text me saying he'd received two report slips from my then wife with different hours (one i'd put in her for and one she'd put in herself). I told him to record whichever was higher. I hint that we're just making it up.
