On another meta question, I mentioned one that I wrote long before that had several up votes. I was asked to link to it. Not long after, it got two more. I guess people followed the link and liked it. Not important.
But what I don't get is the rationale for why one up vote adds five points and another the same day adds ten.
When that user upvoted the answer, you got +10. When they upvoted the question, you got +5.
For reference, check out this post: How does “Reputation” work? All the following is quoted verbatim from there:
You gain reputation when:
- one of your questions is voted up/useful: +5
- one of your answers is voted up/useful: +10
- one of your answers becomes accepted: +15
- you accept an answer written by someone else to one of your own questions: +2
- a downvote on one of your questions or answers is removed: +2
- you [suggest an edit and it is accepted][11]: +2 (up to a total of +1000 per user)
- you remove a downvote from an answer: +1
- an answer you downvoted is removed: +1
- one of your answers is awarded a bounty by the user offering the bounty: +full bounty amount
- one of your answers is awarded a bounty automatically: +½ of the bounty amount (see bounty FAQ for details)
- you associate accounts of two or more Stack Exchange network sites, and at least one of those accounts already has 200 or more reputation: +100 on each site (awarded a maximum of one time per site)
You lose reputation when:
- one of your questions or answers is voted down/not useful: −2
- a post where you had successfully suggested an edit has been deleted (reputation page shows the cause as "removed"): -2
- the account of a user who was the final approver of a suggested edit you made has been deleted (reputation page shows the cause as "User was removed"): -2
- you vote an answer down/not useful: −1
- an upvote on one of your questions is removed: −5
- an upvote on one of your answers is removed: −10
- one of your accepted answers loses accepted status: −15
- you unaccept an answer written by someone else to one of your own questions: -2
- you place a bounty on a question: −full bounty amount
- one of your posts receives 6 [spam][12] or ["it is not welcome in our community" flags][13] (formerly known as offensive flags): −100
