Especially in /new some users use multiple accounts or ask friends to upvote (I think that's called a voting ring). You'd see 9 votes but not all are counted. There seems to be a public number and a hidden "real" number for scoring. Another factor seems to be speed: a story receiving lots of upvotes in the first X (10?) minutes ends up on the homepage faster than one receiving one upvote per hour. Lastly those with 'Ask HN' or 'Show HN' in the title have different behavior and need less upvotes for their respective pages. Certain users (with high karma? or account age?) having more power is an interesting theory, I haven't noticed that yet. But I saw "Moderators and a small number of reviewers go through old submissions" (https://news.ycombinator.com/item?id=26998308 https://news.ycombinator.com/item?id=26998308) so maybe reviewers, whoever that is, upvoting carries more weight.
