Q: How come my vote cap for "First Posts" is lower than others? I was reviewing First Posts just now, and I received the following message after my 20th vote:

Thank you for reviewing 20 First Posts today; come back in 8 hours to continue reviewing.

I see other users, with far lower reputation than me, voting up to 40 times per day.
Why is it I only have 20 votes?  I saw the How does the /review page work? question, but the accepted answer there mentions flag weight, and I was under the impression that Flag Weight is gone (since it is no longer visibile on my profile).
What is the formula that determines the number of First Post votes a person can get per day?

A: We introduced and then fixed a bug over the weekend, which caused a couple thousand erroneous posts to be added to the queue. We usually limit the First Posts queue to posts created within the past 30 days, but that requirement was accidentally lifted for a short while. As a result, the queue size spiked up to around 2000.
Currently, we allow 20 reviews per user per queue per day, but we double this to 40 if the queue size is over 1000. So, the users that reviewed 40 first posts today managed to do so before we fixed the bug.
