I didnt manage to stow 300 packages an hour.

So today was my third day stowing at my DS. I was sweating like the days before, suddenly the ambassador asigned to me comes up to one of my rows with the laptop and the numbers (he said hes gonna do the same with the other newhires.. i talked with them and they were all to slow for him), we looked at the numbers together for the first time. i got 275 and he said its good for the first week, but next week i should try to get to at least 300. i was thinking in my head "bruh touch my back, its soaked in sweat.)
what are your thoughts on this?
Also, i got a 3 month temporary contract with no plans to continue after the 3 months yet.
in my contract its stated theres no probation period where they can kick me out without reason.
so potentially i could take a chill pill and not bust my ass off so hard and do my own pace, right?

sorry for the english, not my native language

Edit: 1 day later, today while stowing my assigned ambassador gave me a thumps up and was like very good and not a single error while stowing.. i thanked him for the positive feedback but didnt ask what rate i was stowing at, i guess it was over 300 today...was the first day i stowed with sweatpants, they make a huge difference lmao. was stowing in baggy jeans before, not very comfortable. :D

also i rlly was able to pull off the sorting on the smart cart today, i like to have a bucket on top where i throw all the E g H J so they dont fall down the cart, and next to the bucket i place the others and occasionally i stowed a b c d as soon as i grabbed them..
