Dunno, that's why grading and the scale is so hard. When I switched it from straight words = cash to a grading scale to reward those that put extra time in (e.g a lot of stats work but that doesn't show up in words), it worked but it's a lot more effort for the grader and sometimes effort of the writer isn't clear.

Tbh, the gfx gods can crank out a 7 or 8/10 in like 30 minutes max, even some closer to average sig makers as well. But that's also getting the same grade as what you spent 4-5 hours on. So how do you compensate for time? You can't really, which makes it hard to up the payment as you'll be over compensating some but at the current point you're under compensating some. What would we rather have?
