Interesting. This pushes the competition for curation rewards into a period between 21 seconds (block 7 after the post - equivalent of 5 mins currently) and 48 seconds (block 16 after the post - equivalent of 12 mins currently). A total of ten blocks.

That could mean a lot of votes in each block for popular authors where curation rewards are high.

Out of interest, how many votes can fit into one Steem block?

Also, what happens if someone sends through a huge post, very close to the block limit, at 30 seconds (or a number of smaller posts of an equivalent size)? Would the votes push into the next block?

Asking for a friend.
