Comment (by arma):

 I can't tell from the graph you gave us that there are any lines with
 granularity of 1. Here's one where it's easier to see:

 transport.html?start=2018-04-14&end=2018-07-20&transport=websocket&transport=snowflake

 I look forward to hearing from Karsten or Iain on this one, but here is a
 reason why it could make sense:

 If you have a multiple of 8 that is much higher than 8, then it makes a
 lot of sense to estimate that you're in the middle of your top multiple
 (i.e. if it says 80 figure 76, if it says 88 figure 84, etc). But if it
 says 8, it's probably not the case that you had 4 users. I could see an
 argument for betting that most of the 8's represent one user, and
 aggregating them that way.
