Will 21 or more people put in a prediction on this market?

I may close this market early if the answer is YES but I won't extend the close date if the answer is NO.

This is the latest version of this market - each time the target increases by one so it should be a bit less of a certain thing. Here's how the previous markets went:

Target hit in 28 hours 47 minutes. This time five non-bot users had positions on NO at the end - the first time that so many people thought that the target might not be hit!

 Target hit in 6 hours 41 minutes - significantly faster than the previous three iterations!
