Haha ok. Giving the exact rent amounts, as well as my first name, and city could be identify information.
No, I was trying to determine if the difference was approximately the amount that you would have paid for the initial prorated amount you paid for your very first month in the unit, or the amount you didn't pay your first month.
If it was the former, then a clear mistake was made on the lease that would be obvious to anyone, they copied too much from the previous lease. If it was the later, then it would not be as clear of mistake and you might have an argument on your side. I could not tell that from just the difference because that does not tell me the ratios.
If you think that you can be identified by your first name, city and amount of rent you pay, then you are living in paranoid land.
