How many cars per hour does your CFA do?

So I’ve been working at CFA for a while and I normally work nights. Our managers and leaders are always talking about getting our night record for number of cars/hour. Normally we hit 170 on average for 3-4 hours on fridays and saturdays. Im just wondering, what are average numbers for other CFAs?

Ive also only been trained for secondary and I have to do secondary alone. Ive been there for 6 months and still havent been trained for anything else. Is this typical or is this just my location?
