I may have had sympathy back in the day of meaningful grading, especially the day of 8 or even 10 grades for 1 TPE.
But why are you even grading more than you need? PTs are just auto 6 so it's not like you're holding anyone up? Just do your 8 when you feel like it and call it a week.
Alternatively, bring back the old scale. Seriously wtf, people get paid 1 TPE for writing 4 lines now? I think we should scale back to 8/10 TPE per grade.
